Abstract (sommario):

Diagnostic electron microscopy is a useful technique for the identification of viruses associated with human, animal, or plant diseases. The size of virus structures requires a high optical resolution (i.e., about 1 nm), which, for a long time, was only provided by transmission electron microscopes operated at 60 kV and above. During the last decade, low-voltage electron microscopy has been improved and potentially provides an alternative to the use of high-voltage electron microscopy for diagnostic electron microscopy of viruses. Therefore, we have compared the imaging capabilities of three low-voltage electron microscopes, a scanning electron microscope equipped with a scanning transmission detector and two low-voltage transmission electron microscopes, operated at 25 kV, with the imaging capabilities of a high-voltage transmission electron microscope using different viruses in samples prepared by negative staining and ultrathin sectioning. All of the microscopes provided sufficient optical resolution for a recognition of the viruses tested. In ultrathin sections, ultrastructural details of virus genesis could be revealed. Speed of imaging was fast enough to allow rapid screening of diagnostic samples at a reasonable throughput. In summary, the results suggest that low-voltage microscopes are a suitable alternative to high-voltage transmission electron microscopes for diagnostic electron microscopy of viruses.

Abstract (sommario):

The observation of microstructural features smaller than 300 nm is generally performed using Transmission Electron Microscopy (TEM) because conventional Scanning Electron Microscopes (SEM) do not have the resolution to image such small phases. Since the early 1990’s, a new generation of microscopes is now available on the market. These are the Field Emission Gun Scanning Electron Microscope with a virtual secondary electron detector. The field emission gun gives a higher brightness than those obtained using conventional electron filaments allowing enough electrons to be collected to operate the microscope with incident electron energy, E0, below 5 keV with probe diameter smaller than 5 nm. At 1 keV, the electron range is 60 nm in aluminum and 10 nm in iron (computed using the CASINO program). Since the electron beam diameter is smaller than 5 nm at 1 keV, the resolution of these microscopes becomes closer to that of TEM.

Abstract (sommario):

This issue of the MRS Bulletin aims to highlight the innovative and exciting materials science research now being done using in situ electron microscopy. Techniques which combine real-time image acquisition with high spatial resolution have contributed to our understanding of a remarkably diverse range of physical phenomena. The articles in this issue present recent advances in materials science which have been made using the techniques of transmission electron microscopy (TEM), including holography, scanning electron microscopy (SEM), low-energy electron microscopy (LEEM), and high-voltage electron microscopy (HVEM).The idea of carrying out dynamic experiments involving real-time observation of microscopic phenomena has always had an attraction for materials scientists. Ever since the first static images were obtained in the electron microscope, materials scientists have been interested in observing processes in real time: we feel that we obtain a true understanding of a microscopic phenomenon if we can actually watch it taking place. The idea behind “materials science in the electron microscope” is therefore to use the electron microscope—with its unique ability to image subtle changes in a material at or near the atomic level—as a laboratory in which a remarkable variety of experiments can be carried out. In this issue you will read about dynamic experiments in areas such as phase transformations, thin-film growth, and electromigration, which make use of innovative designs for the specimen, the specimen holder, or the microscope itself. These articles speak for themselves in demonstrating the power of real-time analysis in the quantitative exploration of reaction mechanisms.The first transmission electron microscopes operated at low accelerating voltages, up to about 100 kV. This placed a severe limitation on the thickness of foils that could be examined: Heavy elements, for example, had to be made into foils thinner than 0.1 μm. It was felt that any phenomenon whose “mean free path” was comparable to the foil thickness would be significantly affected by the foil surfaces, and therefore would be unsuitable for study in situ. However, technology quickly generated ever higher accelerating voltages, culminating in the giant 3 MeV electron microscopes. At these voltages, electrons can penetrate materials as thick as 6–9 μm for light elements such as Si and Al, and 1 μm for very heavy ones such as Au and U.

Abstract (sommario):

The Photoelectron Emission Microscope (PEEM) and Low Energy Electron Microscope (LEEM) are parallel-imaging electron microscopes with highly surface-sensitive image contrast mechanisms. In PEEM, the electron yield at the illumination wavelength determines image contrast, in LEEM, the intensity of low energy (< 100 eV) electrons back-diffracted from the surface, as well as interference effects, are responsible for image contrast. Mirror Electron Microscopy is also possible with the LEEM apparatus. In MEM, no electron penetration into the solid occurs, and an image of surface electronic potentials is obtained.While the emission microscope techniques named above are not high resolution methods, the unique contrast mechanisms, the ability to use thick single crystal samples, their compatibility with uhv surface science methods and new material-growth methods, coupled with real-time imaging capability, make them very useful.These microscopes do not depend on scanning probes, and some are compatible with pressures up to 10-3 Torr and specimen temperatures above 1300K.

Abstract (sommario):

Since publication of the classic text on the electron microscope laboratory by Anderson, the proliferation of microscopes with field emission guns, imaging filters and hardware spherical aberration correctors (giving higher spatial and energy resolution) has resulted in the need to construct special laboratories. As resolutions iinprovel transmission electron microscopes (TEMs) and scanning transmission electron microscopes (STEMs) become more sensitive to ambient conditions. State-of-the-art electron microscopes require state-of-the-art environments, and this means careful design and implementation of microscope sites, from the microscope room to the building that surrounds it. Laboratories have been constructed to house high-sensitive instruments with resolutions ranging down to sub-Angstrom levels; we present the various design philosophies used for some of these laboratories and our experiences with them. Four facilities are described: the National Center for Electron Microscopy OAM Laboratory at LBNL; the FEGTEM Facility at the University of Sheffield; the Center for Integrative Molecular Biosciences at TSRI; and the Advanced Microscopy Laboratory at ORNL.

Abstract (sommario):

Electrons have undoubtedly been around since the beginning of time, but not until the first quarter of the twentieth century, following the work of deBroglie on the dual nature of the electron, Busch's hypothesis that an electron beam could be focussed by an axially symmetric magnetic field, and Davisson & Germer's and Thomson's independent demonstrations of electron diffraction, did microscopists take seriously the possibility of a microscope utilizing electrons and magnetic fields. The first attempts at building electron microscopes were made in Europe but the resolution in the often blurred and distorted electron images was not much better than that achieved by light microscopy, so that a general opposition to funding the development of electron microscopes began to emerge. In 1935 E.F. Burton, Chairman of the Department of Physics at the University of Toronto began a program of electron optical research with his graduate student Cecil E. Hall, building emission microscopes.

Abstract (sommario):

With the recent development of ultra-high vacuum high resolution electron microscopes (UHV-HREM), electron microscopes have become valuable tools for surface studies. Techniques such as surface profile image, surface sensitive plane view, and reflection electron microscopy have been developed to take full advantage of the atomic resolution of HREM to study surface structures. However a complete surface study requires information on both the surface structure and surface chemistry. Therefore in order to turn an electron microscope into a real surface analytical tool, the challenge is to develop a microscopecompatible, surface sensitive tool for in-situ surface chemical analysis.

Abstract (sommario):

Historically, ultra high spatial resolution electron microscopy has belonged to the transmission electron microscope. Today, however, ultra high resolution scanning electron microscopes are beginning to challenge the transmission microscope for the highest resolution.To accomplish high resolution surface imaging, not only is high resolution required. It is also necessary that the integrity of the specimen be preserved, i.e., that morphological changes to the specimen during observation are prevented. The two major artifacts introduced during observation are contamination and beam damage, both created by the small, high current-density probes necessary for high signal generation in the scanning instrument. The JSM-890 Ultra High Resolution Scanning Microscope provides the highest resolution probe attainable in a dedicated scanning electron microscope and its design also accounts for the problematical artifacts described above.Extensive experience with scanning transmission electron microscopes lead to the design considerations of the ultra high resolution JSM- 890.

Abstract (sommario):

Tato práce se zabývá možnostmi kvantitativního zobrazování ve skenovacím (transmisním) elektronovém mikroskopu (S|T|EM) společně s jejich korelativní aplikací. Práce začíná popisem metody kvantitativního STEM (qSTEM), kde lze stanovenou lokální tloušťku vzorku dát do spojitosti s ozářenou dávkou, a vytvořit tak studii úbytku hmoty. Tato metoda byla použita při studiu ultratenkých řezů zalévací epoxidové pryskyřice za různých podmínek (stáří, teplota, kontrastování, čištění pomocí plazmy, pokrytí uhlíkem, proud ve svazku). V rámci této části jsou diskutovány a demonstrovány možnosti kalibračního procesu detektoru, nezbytné pozadí Monte Carlo simulací elektronového rozptylu a dosažitelná přesnost metody. Metoda je pak rozšířena pro použití detektoru zpětně odražených elektronů (BSE), kde byla postulována, vyvinuta a testována nová kalibrační technika založená na odrazu primárního svazku na elektronovém zrcadle. Testovací vzorky byly různě tenké vrstvy v tloušťkách mezi 1 až 25 nm. Použití detektoru BSE přináší možnost měřit tloušťku nejen elektronově průhledných vzorků jako v případě qSTEM, ale také tenkých vrstev na substrátech - qBSE. Obě výše uvedené metody (qSTEM a qBSE) jsou založeny na intenzitě zaznamenaného obrazu, a to přináší komplikaci, protože vyžadují správnou kalibraci detektoru, kde jen malý posun úrovně základního signálu způsobí významnou změnu výsledků. Tato nedostatečnost byla překonána v případě qSTEM použitím nejpravděpodobnějšího úhlu rozptylu (zachyceného pixelovaným STEM detektorem), namísto integrální intenzity obrazu zachycené prstencovým segmentem detektoru STEM. Výhodou této metody je její použitelnost i na data, která nebyla předem zamýšlena pro využití qSTEM, protože pro aplikaci metody nejsou potřeba žádné zvláštní předchozí kroky. Nevýhodou je omezený rozsah detekovatelných tlouštěk vzorku způsobený absencí píku v závislosti signálu na úhlu rozptylu. Obecně platí, že oblast s malou tloušťkou je neměřitelná stejně tak jako tloušťka příliš silná (použitelný rozsah je pro latex 185 - 1 000 nm; rozsah je daný geometrií detekce a velikostí pixelů). Navíc jsou v práci prezentovány korelativní aplikace konvenčních a komerčně dostupných kvantitativních technik katodoluminiscence (CL) a rentgenové energiově disperzní spektroskopie (EDX) spolu s vysokorozlišovacími obrazy vytvořenými pomocí sekundárních a prošlých elektronů.

Abstract (sommario):

Electron vortex beams (EVBs) are electron beams with a doughnut-like intensity profile, carrying orbital angular momentum due to their helical phase shift distribution. When employed in an electron microscope, they are expected to be efficient for the detection of magnetic signals. In this report I have investigated high angle annular dark field (HAADF) images obtained using EVBs. This was done for 300 K and 5K. For 5 K, I also compared HAADF images from an ordinary electron beam with HAADF images from an electron vortex beam. What was found was that EVBs produced doughnuts around the atomic columns. However, when taking the size of the electron source into account, this phenomena could no longer be observed. When comparing images from EVBs with images from ordinary electron beams, I found that the intensity of scattered electrons around atomic columns was broader for EVBs. This was persistent even after taking the source size into account.
Elektronvirvelstrålar (EVS) är elektronstrålar med en munk-liknande intensitetsprofil. Dessa bär på rörelsemängdsmoment på grund av sin fasdistribution. När de används i ett elektronmikroskop förväntas de vara effektiva för detektering av magnetiska signaler. I denna uppsats har jag undersökt high angle annular dark field (HAADF) bilder som erhållits med hjälp av EVS. Detta gjordes för 300 K och 5K. För 5 K, jämförde jag även HAADF bilder från en vanlig elektronstråle med HAADF bilder från en elektronvirvelstråle. Vad jag fann var att EVS producerade en munkformad intensitetsfördelning runt atomerna. Men när hänsyn till storleken på elektronkällan togs i beaktande kunde inte detta fenomen observeras längre. När bilder från EVS jämfördes med bilder från vanliga elektronstrålar, fann jag att intensiteten av spridda elektroner runt atomkolumnerna var bredare för EVS. Detta kunde observeras även efter att jag tagit hänsyn till elektronkällans storlek.

Abstract (sommario):

The technique of Nanoindentation in situ Transmission Electron Microscope has been implemented on a Philips CM20. Indentations have been performed on Si and Sapphire (α-Al2O3) cut from wafers; Cr/Sc multilayers and Ti3SiC2 thin films. Different sample geometries and preparation methods have been evaluated. Both conventional ion and Focused Ion Beam milling were used, with different ways of protecting the sample during milling. Observations were made of bending and fracture of samples, dislocation nucleation and dislocation movement. Basal slip was observed upon unloading in Sapphire. Dislocation movement constricted along the basal planes were observed in Ti3SiC2. Post indentation electron microscopy revealed kink formation in Ti3SiC2 and layer rotation and slip across layers in Cr/Sc multilayer stacks. Limitations of the technique are presented and discussed.

Abstract (sommario):

Holography has been used in electron microscopy since the field emission electron microscope was developed.[1] Tonomura et al described the interference microscope based on the electron holography to evaluate microscopic distribution of the magnetic field. [2] To gain high sensitivity the use of the optical phase multiplication technique was discussed so as to obtain 10 time magnification of the reconstructed phase. [3] Recently Takeda et al applied the FFT method of the subfringe analysis for electron holographic fringes.[4] They mentioned phase variations much smaller than 2 π could be detected without recource to optical reconstruction or optical interferometric measurements.

Abstract (sommario):

Abstract Energy-dispersive X-ray spectrometry (EDS) is a key analytical tool aiding root cause determination in the failure analysis (FA) process. This paper looks at a number of analytical TEM microscopes currently in use in various facilities: microscope A, a STEM operated at 200kV; microscope B, a 300kV TEM; and microscopes C and D, both 200kV TEMs. EDS counts per unit time from multiple microscope platforms were examined. Microscope D demonstrated two orders of magnitude higher counts per unit time than the other three microscopes. Microscope D represents the state-of-the-art EDS analytical TEM configuration and has achieved this through a novel windowless EDS configuration which significantly increases the detector area (by about a factor of three) that receives X-rays generated from the sample.
