Abstract:
In situ hot-stage high-resolution transmission electron microscopy (HRTEM) provides unique capabilities for quantifying the dynamics of interfaces at the atomic level. Such information complements detailed static observations and calculations of interfacial structure, and is essential for understanding interface theory and solid-state phase transformations. This paper provides a brief description of particular requirements for performing in situ hot-stage HRTEM and illustrates the use of this technique to obtain quantitative data on the atomic mechanisms and kinetics of interface motion during precipitation of {111} θ phase in an Al-Cu-Mg-Ag alloy.The specimen and microscope requirements for in situ hot-stage HRTEM are not much different from those of static HRTEM, except that one must have a heating holder and equipment for recording and analyzing dynamic images. At present, most HRTEMs are equipped with a TV-rate camera, possibly combined with a charge-coupled device camera. An inexpensive way to record in situ HRTEM images is to send the output from the TV-rate camera directly into a standard VHS format videocassette recorder (VCR).

Abstract:
AbstractA technique for preparing vermiculites for examination by high-resolution transmission electron microscopy (HRTEM) has been developed. A TEM-stable expanded phase can be obtained by intercalating n-alkylammonium ions between the silicate layers of a parent biotite. The vermiculite particles were embedded in Spurr resin and centrifuged to improve orientation. Ultra-thin specimens were prepared using an ultramicrotome, the quality and thickness of the sections being monitored by TEM. Lattice images of biotite, Ba-vermiculite and octylammonium-vermiculite, the latter showing a perpendicular arrangement of the alkyl chains relative to the silicate layers, were obtained with a resolution ∼2 Å. The reliability of these images was confirmed by computer simulation.

Abstract:
Image simulation has become one of the preferred techniques for analysis of high-resolution transmission electron micrographs, in both bright-field and dark-field modes. This is especially true of microscope images used in stuctural studies, both for perfect crystal structures, and for defects within periodic structures. In using image simulation for structural analysis, comparison is made point-by-point (pixel by pixel) between the experimental image and one simulated under identical imaging conditions for a model structure. Comparison with a matching simulated image enables features in the experimental image to be identified as belonging to structural features in the specimen, such as groups of atoms, or individual atoms. In the case of amorphous structures, however, no such one-to-one correspondence between simulations and experimental high-resolution images can be expected. It is thus much more difficult to determine whether the model from which one is simulating images really does describe the appropriate amorphous structure. Amorphous structures are characterized not in terms of atom positions within a well-defined unit cell, but interms of a “radial distribution function” (RDF), a function that gives the average number of atoms lying at any given distance from an average atom. The RDF is thus a non-periodic Patterson function, and a single RDF can arise from many different arrangements of atoms, provided only that atomic positions within the structure have the “right” statistical distribution.

Abstract:
The goal of this Master thesis is to design a power convertor for BLDC motor 48V/2kW. Emphasis is placed on the small dimensions of the final printed circuit board. Therefore, power SMD transistors STL135N8F7AG are used in small packages PowerFlat 5x6. To reduce area of the PCB, electrolytic capacitors are mounted on a separate board, which is located above the main PCB. Small high-capacity 22F/100V ceramic capacitors are used in the DC-LINK as well. They are located as close as possible to the power SMD tranzistors. Control logic will be provided by microprocesor STM32G474RE. High resolution timer HRTIM1 is used. The first part of this thesis is devoted to the brief description of BLDC motor construction and driving. Next parts are focused on the design itself.

Abstract:
Three-dimensional porous single crystals (PSCs) are a recent development in the growing world of mesoporous material. The mesoporosity allows for the material to retain their nanoproperties whilst being bulk in size. The current work concentrates on chromium oxide and cobalt oxide PSCs formed in the templates SBA-15 and KIT-6. HRTEM is the main technique used in this investigation, looking at the morphology and single crystallinity of these materials. A growth mechanism for the PSC material is proposed based on HRTEM observations. XRD studies revealed that the confinement effect, caused by the mesopores, reduces the temperature for both cobalt and chromium oxide crystallisation, as well as a different intermediate route from the metal nitrates. The properties of chromium oxide PSC are also investigated magnetically and catalytically. Some metal oxides in different templates are also presented, despite no PSC forming. HRTEM work on other nanomaterials, based on collaboration, is also presented.

Full text
Abstract:
In the present study, the formation and the evolution of lamellar structures in different Al-Ag alloys were investigated by transmission electron microscopy (TEM). Plates of the hexagonal [gamma] phase form semi-coherently on the {111} planes of the face centered cubic lattice of the alloy after the formation of Guinier-Preston zones. Guinier-Preston zones are metastable coherent preprecipitates which are silver rich in the aluminum-rich Al-Ag alloys. The decomposition of aluminum rich Al-Ag alloys, particularly the sequence of the later stages of precipitate formation was studied. With scanning electron microscopy and high-resolution transmission electron microscopy the development of the [gamma] phase was investigated. Samples cut from different Al-Ag alloys were homogenized at temperatures between 530 degrees C to 560 degrees C to obtain a single phase f.c.c solid solution. The samples were then quenched to room temperature, followed by heat treatments at temperatures between 140 degrees C and 220 degrees C for varying lengths of times. While Guinier-Preston zones increase in diameter with increasing aging duration, silver rich platelets of the [gamma] phase form. The [gamma] phase is the next metastable phase in the decomposition sequence before finally the [gamma] phase transforms to the stable silver-rich phase, termed [gamma]. For samples with silver contents above 12 at.% a parallel lamellar alignment of fine [gamma] plates and Alrich matrix is found after extended heat treatments. For all alloys with Ag concentrations below 12 at.% individual [gamma] plates are found on all four possible (111) planes of the [alpha] matrix. A method is presented to calibrate the medium-magnification high-angle annular dark-field contrast in scanning transmission electron microscopy. This calibration allows for the quantitative measurement of plate thicknesses from high-angle annular dark-field scanning transmission electron micrographs of Ag2Al plates inclined to the electron beam. Results from these measurements are in good agreement with direct bright-field micrographs of plates viewed edge-on.

Full text
Abstract:
La aleación Cu-11,8%p.Al-0,5%p.Be presenta un comportamiento de Memoria de Forma (MF) del tipo Superelástico. Este último consiste en que al aplicar carga, dentro de ciertas condiciones, se tienen deformaciones relativamente importantes (2-8%) que se recuperan al retirar la carga. El fenómeno de MF se asocia a una transformación martensítica, la que involucra una fase madre austenita (β), de alta simetría, y a una fase metaestable martensita (β’), de baja simetría. En un ciclo de carga y descarga, las aleaciones superelásticas disipan energía. Este comportamiento de disipación y la capacidad de aceptar grandes deformaciones recuperables, da la potencialidad de que estos materiales puedan actuar como disipadores de energía, por ejemplo, en estructuras civiles. Según nuestro conocimiento, no existen estudios publicados de la aleación CuAlBe en el rango post-superelástico, donde ya hay deformaciones remanentes. De modo que para ese rango se desconoce la microestructura del material y de qué forma se comporta la disipación de energía. En este trabajo se analizaron cuatro casos de distinta deformación en la aleación CuAlBe, a temperatura ambiente y para un tamaño de grano de 100 um. En el primer caso se deformó una probeta en el rango superelástico (0,23% de deformación) mediante un ensayo monotónico. En el segundo caso se impuso una deformación del 6% en ensayos monotónico y cíclico (a dos distintas probetas), en el tercero se impuso una deformación del 9% en ensayos monotónico y cíclico (a dos distintas probetas); y en el cuarto se llevó una probeta hasta la fractura. En ensayos de tracción monotónicos, se determinó que el módulo de Young del material es de 88GPa, que la resistencia a la fractura es de 802MPa, y que la fractura corresponde a una deformación de 10.2%, con carga. También se determinó, mediante un método de derivadas, validado por información y datos de otros estudios, que el límite superelástico de esta aleación, a temperatura ambiente, corresponde a una deformación de 2.5%. Los resultados anteriores son concordantes con estudios anteriores. En ensayos de tracción cíclicos (0,5 y 1 Hz) se encontró que en el rango post-superelástico existe elasticidad no lineal y amortiguamiento, siendo este último mayor que en el rango superelástico. Se obtuvo metalografías de los distintos casos de deformación ya definidos. En el primer caso, dentro del rango superelástico, no se observó martensita remanente, solo austenita, como era de esperar. Por otra parte, en los casos 2, 3 y 4, en el rango post-superelástico, se observó austenita con martensita remanente y que la fracción de esta última crecía con la deformación impuesta. En la fractografías del caso 4, se observó preferentemente fractura transgranular, con zonas de clivaje y otras de hoyuelos, lo cual es un resultado conocido. En microscopia electrónica de transmisión, se observó muestras vírgenes y con deformación. En ambos tipos de muestra se estableció que la austenita presenta finas franjas, las que corresponderían a defectos cristalinos que podrían estar relacionados con manchas de difracción alargadas adicionales al patrón de difracción BCC de esa fase. En muestras con deformación, en la austenita se observó dislocaciones apareadas, denominadas dislocaciones de superred; además se observaron franjas gruesas en la austenita que es posible que sean vestigios de placas revertidas de martensita inducidas por deformación. Se concluye que la elasticidad no lineal observada en el rango post-superelástico se asocia a la austenita aún presente en ese rango, la que podría transformarse por esfuerzo en martensita. Además, el mayor amortiguamiento observado en el rango post-superelástico, en relación con aquel en el rango elástico, estaría relacionado con los defectos cristalinos observados en la austenita, al requerir ellos una mayor energía para que ocurra la transformación martensítica.

Abstract:
Defective structures in two-dimensional (2D) materials have been proved to have significant influences on the materials' properties. Understanding structural defects in 2D materials at atomic scale is therefore required. With the use of advanced imaging techniques, one of the main approaches applied in this project was aberration-corrected transmission electron microscopy (AC-TEM), the structures are able to be resolved with single-atom sensitivity with the reduction of both spherical aberration and the influence of chromatic aberration. This laid the foundation for the first two experiments, which involve the bond length measurement of each C-C bond within three types of divacancies and Si-C bonds at graphene edges. The former explains the tendency of bond rotations within the divacancies from the perspective of strain inside the defective areas and surrounding lattice; the latter revels the interactions between isolated Si atoms and zigzag/armchair graphene edges. The use of in-situ heating holder in the AC-TEM makes the direct visualization of structures and their dynamics at elevated temperatures possible. The Si-graphene edge interactions, as well as the following two experiments are all designed to study the high-temperature performances for different systems. Gold nanoclusters are introduced to monolayer graphene by thermal evaporation to study the interaction between gold and graphene at elevated temperature. Due to the strong interaction between gold and graphene, gold crystals are able to adapt to planar configurations with two different crystalline forms, and an epitaxial relationship was found for planar gold crystals and graphene. Atomically flat and long line defects and zigzag edges in monolayer molybdenum disulfide (MoS2) are successfully created by in-situ thermal annealing. The relationship between S vacancy mobility and defect forms are revealed based on the experiment. High-temperature atomic configurations of line defects and edge terminations are resolved in the first time. Their electronic properties are also explored with the support of density functional theory calculations.

Abstract:
Un nouveau facteur de transcription, appartenant à la famille des protéines à domaine bHLH, a récemment été isolé dans notre laboratoire. Initialement appelé « clone bc8 » puis HRT1, ce facteur présentait des similitudes avec les protéines Hairy and Enhancer of split qui interviennent notamment dans le phénomène d’inhibition latérale lors de la formation du tissu neural. Des études d’hybridation in situ réalisées chez l'embryon de xénope ont suggéré un rôle important de XHRT1, la protéine HRT1 de xénope, dans le développement neural. Nous avons recherché les partenaires protéiques de XHRT1 par la technique du double-hybride afin de mieux comprendre son mécanisme d’action moléculaire dans la neurogenèse.

Tout d’abord nous avons construit les outils appropriés pour l’élaboration du travail, à savoir, les clones de levures exprimant les appâts spécifiques des domaines de la protéine étudiée et la création d’une banque d’ADNc du xénope au stade de la neurulation. Ensuite, trois criblages ont été réalisés. Dans le premier cas, nous avons recherché les partenaires des domaines bHLH et Orange (bHLH-O). Le domaine bHLH est en effet responsable de la dimérisation de ce type de protéine. Le domaine Orange qui suit le domaine bHLH, pourrait participer dans le choix du partenaire d’hétérodimérisation. Nous avons isolé deux facteurs de type bHLH-Orange apparentés à HRT1, XHairy1 et XHairy2b et confirmé leur interaction avec XHRT1. Les domaines impliqués dans ces interactions sont les bHLH-O pour les trois facteurs. Ce même criblage nous a permis d’isoler un nouvel ADNc qui code une protéine sans domaine apparent connu actuellement. Nous avons montré que cette protéine reconnaissait spécifiquement le domaine Orange de HRT1 mais pas celui des autres facteurs de type bHLH-O. Elle a été baptisée BOIP pour Bc8 Orange Interacting Protein. Le rôle physiologique de cette interaction n’a pu être démontré. Nous avons établi que la protéine BOIP pouvait aussi s’homodimériser. Nous avons aussi déterminé son profil d’expression chez le xénope et la souris. Son transcrit est hautement présent dans les testicules adultes. La protéine pourrait donc jouer un rôle important dans la spermatogenèse. Les deux autres criblages, utilisant les domaines situés dans la partie C-terminale de XHRT1, ont apporté des nouveaux partenaires potentiels, mais ces interactions n’ont pu être confirmées dans un système indépendant.

Enfin, en étudiant plus en détail les interactions entre XHRT1 et XHairy1 ou XHairy2b, nous avons mis à jour une possible fonction de spécificité dans le choix du partenaire dans la région C-terminale de HRT1. La formation de ces dimères pourrait jouer un rôle dans la formation du tube neural mais également dans d’autres différenciations tissulaires.

Abstract:
The structural analysis serves as a bridge to link the structure of materials to their properties. Revealing the structure details allows a better understanding on the growth mechanisms and properties of materials, and a further designed synthesis of functional materials. The widely used methods based on X-ray diffraction have certain limitations for the structural analysis when crystals are small, poorly crystallized or contain many defects. As electrons interact strongly with matter and can be focused by electromagnetic lenses to form an image, electron crystallography (EC) approaches become prime candidates for the structural analysis of a wide range of materials that cannot be done using X-rays, particularly nanomaterials with poor crystallinity. Three-dimensional electron diffraction tomography (3D EDT) is a recently developed method to automatically collect 3D electron diffraction data. By combining mechanical specimen tilt and electronic e-beam tilt, a large volume of reciprocal space can be swept at a fine step size to ensure the completeness and accuracy of the diffraction data with respect to both position and intensity. Effects of the dynamical scattering are enormously reduced as most of the patterns are collected at conditions off the zone axes. In this thesis, 3D EDT has been used for unit cell determination (COF-505), phase identifications and structure solutions (ZnO, Ba-Ta3N5, Zn-Sc, and V4O9), and the study of layer stacking faults (ETS-10 and SAPO-34 nanosheets). High-resolution transmission electron microscope (HRTEM) imaging shows its particular advantages over diffraction by allowing observations of crystal structure projections and the 3D potential map reconstruction. HRTEM imaging has been used to visualize fine structures of different materials (hierarchical zeolites, ETS-10, and SAPO-34). Reconstructed 3D potential maps have been used to locate the positions of metal ions in a woven framework (COF-505) and elucidate the pore shape and connectivity in a silica mesoporous crystal. The last part of this thesis explores the combination with X-ray crystallography to obtain more structure details.

Abstract:
Abstract The aggressive scaling of metal oxide semiconductor field effect transistor (MOSFET) device features, including gate dielectrics, silicides, and strained Si channels, presents unique metrology and characterization challenges to control electrical properties such as reliability and leakage current. This paper describes challenges faced in measuring the thickness of thin gate oxides and interfacial layers found in high-K gate dielectrics, determining Ni silicide phase in devices, and characterizing strain in MOSFETs with SiGe stressors. From case studies, it has been observed that thin layers (gate oxide, high-K film thickness, and interfacial layer) can be measured using high-resolution transmission electron microscopy (HRTEM) with good accuracy but there are some challenges in the form of sample thickness, damage-free samples, and precise sectioning of the sample for site-specific specimens. Complementary information based on HRTEM, annular dark field, and image simulation should be used to check the accuracy of thin gate dielectric measurements.
