151-0840-00L | Principles of FEM-Based Optimization and Robustness Analysis | W | 5 credits | 2V + 2U | B. Berisha, P. Hora, N. Manopulo | |
Abstract | The course provides fundamentals of stochastic simulation and non-linear optimization methods. Methods of non-linear optimizaion for complex mechanical systems will be introduced und applied on real processes. Typical applications of stochastical methods for the prediction of process stability and robustness analysis will be discussed. | |||||
Objective | Real systems are, in general, of non-linear nature. Moreover, they are submitted to process parameter variations. In spite of this, most research is performed assuming deterministic boundary conditions, in which all parameters are constant. As a consequence, such research cannot draw conclusions on real system behavior, but only on behavior under singular conditions. Hence, the objective of this course is to give an insight into stochastic simulations and non-linear optimization methods. Students will learn mathematical methods e.g. gradient based and gradient free methods like genetic algorithm, and optimization tools (Matlab Optimization Toolbox) to solve basic optimization and stochastic problems. Furthermore, special attention will be paid to the modeling of engineering problems using a commercial finite element program e.g. LS-Dyna to evaluate the mechanical response of a system, and an optimization tool e.g. LS-Opt for the mathematical optimization and robustness analysis. | |||||

Abstract | Theory, applications, and simulation methods of fluids away from the continuum limit. The focus is on rarefied gases, but applications to micro-fluid mechanics will also be addressed. | |||||
Objective | Fluids are usually treated in the continuum limit. For example, this assumption underlies the Navier-Stokes equations. For certain applications, this is not appropriate; when either the gas becomes so dilute that the molecules' mean-free path is comparable to external length scales (such as for hypersonic flight in the upper atmosphere), or when the external length scales become so small as to approach the molecular length scales (microfluid mechanics). Students will learn: - Relationship between the molecular nature of fluids and macroscopic quantities - Underlying assumptions and approximations of continuum fluid mechanics in general and the Navier-Stokes equation in particular - Theoretical and numerical approaches to treat non-continuum flows | |||||

227-0159-00L | Quantum Transport in Nanoscale Devices | W | 6 credits | 2V + 2U | M. Luisier | |
Abstract | This class offers an introduction into quantum transport theory, a rigorous approach to electron transport at the nanoscale. It covers different topics such as bandstructure, Wave Function and Non-equilibrium Green's Function formalisms, and electron interactions with their environment. Matlab exercises accompany the lectures where students learn how to develop their own transport simulator. | |||||

At this size, electrons do not behave as particle any more, but as propagating waves and the classical representation of electron transport as the sum of drift-diffusion processes fails. The purpose of this class is to explore and understand the displacement of electrons through nanoscale device structures based on state-of-the-art quantum transport methods and to get familiar with the underlying equations by developing his own nanoelectronic device simulator. | |||||
Content | The following topics will be addressed: - Introduction to quantum transport modeling - Bandstructure representation and effective mass approximation - Open vs closed boundary conditions to the Schrödinger equation - Comparison of the Wave Function and Non-equilibrium Green's Function formalisms as solution to the Schrödinger equation - Self-consistent Schödinger-Poisson simulations - Quantum transport simulations of resonant tunneling diodes and quantum well nano-transistors - Top-of-the-barrier simulation approach to nano-transistor - Electron interactions with their environment (phonon, roughness, impurity,...) - Multi-band transport models | |||||
