Hong, Yuanzhuo. « Charge transport properties of graphene and its aligned heterostructures ». Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASP020.
Texte intégralGraphene has unique band structure that conduction band and valence band touch at the Dirac points K and K', making it a zero gap semiconductor. The band structure can be modified by introducing periodic potential (superlattice) that place graphene on top of BN to crystallographic alignment. In this thesis, I mainly discuss the charge transport properties of graphene and its heterostructures. Different sample fabrication methods are introduced to make stacks depending on experiment purpose. We use different transport techniques in monolayer/bilayer graphene and their alignment heterostructures to study different scattering mechanisms in order to understand if these are modified by the presence of the superlattice. We found that small angle scattering is dominant in both monolayer and bilayer graphene samples. Through the transverse magneto focusing (TMF) measurements, we have the conclusion that electron-electron scattering is in dominance of TMF suppression. However, we observe nonidentical response in 0 ̊ and 60 ̊ alignment for bilayer graphene in TMF. This shows the different band structure of two alignments and tell us that the symmetry of bilayer graphene/BN heterostructure is not 60 ̊.We further observe the same nonidentical response in valley Hall effect (VHE) that 60 ̊ alignment doesn't give us the cubic relation which represents the VHE. This fact tells us the three fold symmetry of bilayer graphene/BN and also show that Berry curvature is not the only explanation of VHE. Here we propose a possible explanation about atomic structure relaxation. The strain on the second layer of graphene is different and create gauge fields that act as different pseudo magnetic field and indeed affect the VHE

Texte intégralHall effect thrusters are used for station-keeping of satellites in geostationary orbit. The originality of this kind of thruster is the use of a magnetic field which traps the electrons and creates a high electric field region. In this region, the ions are accelerated and extracted from the plasma to provide a thrust. Electron transport across the magnetic field lines is a major issue in predicting the thruster performance. Several transport mechanisms as collision phenomena and plasma turbulence have been identified to play a role but their exact contribution is still not clear. Based on two numerical particle models ("Particle-In-Cell"), composed of an explicit and implicit trajectory-tracking schemes, this work thesis aims at analyzing the proceeding of a discharge in order to isolate the transport mechanisms of electrons. It also aims at providing a better understanding of the plasma turbulence on the discharge behavior. We emphasize the strong unstationnary character of the discharge. We also study a particular transport mechanism, governed by turbulence and volumic collisions, using a particle-test numerical model

Texte intégralAs part of this thesis, we studied a family of Hall effect sensors , composed of submicrometers Hall cross and microgradiometers made from optimized quantum wells. The first one left this thesis is dedicated to manufacture and to characterization of sensors. They will study everything of manners the resistance of contacts and the depletion length restricting the functioning of sensors In second part, we study the tunnel effect of electrons between the edges of the sample. In the presence of a quantizing magnetic field, at the transition between two quantized Hall plateaus, a succession of sharp peaks is detected in the Hall signal RH and in the longitudinal resistance RL. The peaks appearing on the high-í side of the RL transition appear to be different from the peaks appearing on the low-í side. They mainly differ by their temperature dependence. On the high-í side of the RL transition, the temperature evolution of the peaks is typical for resonant tunneling through a single state in one of the antidots that are progressively formed when the initially occupied LL is emptied. On the low í of the transition, by contrast, the temperature dependence is different. This may be related to the asymmetry of the density of states

Texte intégralOne of the greatest challenges in space exploration is to develop spacecrafts capable of covering great distances with little fuel. Electric thrusters, among which is the Hall effect thruster, are capable of this thanks to their high exhaust velocity. During my PhD, I have tried to understand the physics involved in these thrusters, by means of numerical models and accurate diagnostics. My hosting group has been working on hybrid modeling of these thrusters for about ten years. However, the electron fluid description in such models is still a challenge. One of the problems of the fluid model is the difficulty of solving the fluid equations in 2D. This first problem has been overcome by using a new algorithm. This algorithm makes it now easier to study thrusters with complex magnetic fields. The second problem concerns electron transport which is not well understood. A deep study of a fully particle model in the axial and azimuthal directions has shown that an azimuthal electric field wave, present in the thruster, enhances the electron transport. Also, I have developed a new method to extract the electric field and ionization term profiles from laser spectroscopy measurements. The comparison between these results and those obtained with our hybrid model shows the limit of the electron transport description used until now. This comparison has also shown a possible path to follow in order to correctly describe the electron transport in hybrid models for Hall effect thrusters

Texte intégralAlfvén waves propagating in plasma along an ambient magnetic field are studied in the framework of the magnetohydrodynamics including the Hall Effect (Hall-MHD), which extends the usual MHD to scales comparable to the ion inertial length and to frequencies close to the ion-cyclotron resonance. The validity of Hall-MHD, along with the properties of these waves which in this frequency domain become dispersive, that are exact solutions of the Hall-MHD equations, are subject to various instabilities, giving rise to strong nonlinear phenomena. After discussing the one-dimensional case, attention is paid to three-dimensional configurations. The transverse instability and the collapse of a small-amplitude Alfvén wave resulting in the formation of intense magnetic filaments, predicted by the Nonlinear Schrödinger model and then shown to also occur within the full Hall-MHD system. This “filamentation” phenomenon is nevertheless modified by the presence of quasi-transverse instabilities that inhibits the field amplification and favor the generation of strong density gradients. When the Alfvén wave generates a quasi-incompressible flow at large longitudinal scales that, after averaging on the scale of the wave, is described by the « reduced-MHD » model. Increasing the dispersion, this quasi-two-dimensional flow is replaced by a fully three-dimensional turbulence

Texte intégralThe space propulsion has been a political issue in the midst of the Cold War and remains nowadays a strategic and industrial issue. The chemical propulsion on rocket engines is limited by its ejection velocity and its lifetime. Electric propulsion and more particularly Hall effect thrusters appear then as the most powerful and used technology for space satellite operation. The physic inside a thruster is complex because of the electromagnetic fields and important collision processes. Therefore, all specificities of the engine operation are not perfectly understood. After hundreds of hours of tests, thruster walls are curiously eroded and electromagnetic instabilities are developping within the ionization chamber. The measured electron mobility is in contradiction with the analytical models and raises issues on the plasma behavior inside the discharg chamber. As a result, the AVIP code was developed to provide a massively parallel and unstructured 3D code to Safran Aircraft Engines modeling unsteady plasma inside the thruster. Lagrangian and Eulerian methods are used and integrated in the solver and my work has focused on the development of a fluid model which is faster and therefore better suited to industrial conception. The model is based on a set of equations for neutrals, ions and electrons without drift-diffusion hypothesis, combined with a Poisson equation to describe the electric potential. A rigorous expression of collision terms and a precise description of the boundary conditions for sheaths have been established. This model has been implemented numerically in an unstructured formalism and optimized to obtain good performances on new computing architectures. The model and the numerical implementation allow us to perform a real Hall effect thruster simulation. Overall operating properties such as the acceleration of the ions or the location of the ionization zone are captured. Finally, a second application has successfully reproduced azimuthal instabilities in the Hall thruster with the fluid model and justified the role of these instabilities in the anomalous electron transport and in theerosion of the walls
