Computer Simulation of Electron Energy States for Three-Dimensional InAs/GaAs Semiconductor Quantum Rings

Li Y., Voskoboynikov O., Lee C.P., National Nano Device Laboratories, TW

In this article we study the electron energy states for three-dimensional (3D) semiconductor quantum rings. Our model formulation includes: (i) the effective one-band Hamiltonian approximation, (ii) the position and energy dependent quasi-particle effective mass approximation, [...]

A Parallel Computational Technique for High Frequency HBT Circuit Simulation

Li Y., Huang K-Y, Chen C-K, Lee C.P., National Nano Device Laboratories, TW

We present a parallel-in-waveform simulation technique for high frequency heterojunction bipolar transistor (HBT) circuit characterization. On the contrary to the conventional frequency domain analysis, the HBT circuit equations are solved with waveform relaxation and monotone [...]

Time-Domain Reduced-Order Models of Lateral Viscous Damping Effects for 3-D Geometries

Yen P-C, Yang Y-J, National Taiwan University, TW

A methodology of generating time-domain reduced-order models of viscous lateral damping effects for microsystems is presented. A three-dimensional finite-difference-method (FDM) Stokes flow solver was developed and verified. The system matrices generate by the solver were [...]

Macromodel Extraction of Gas Damping Effects for Perforated Surfaces with Arbitrarily-Shaped Geometries

Yang Y-J, Yu C-J, National Taiwan University, TW

In this work, we present an application of an Arnoldi-based model order reduction (MOR) technique on squeezed-film damping (SQFD) effects for arbitrarily-shaped perforated geometries. The compact models generated by this approach not only can be [...]

Spin Dependent Boundary Conditions and Spin Splitting in Cylindrical Quantum Dots

Li Y., Liu J-L., Voskoboynikov O., Liu J-L., Lee C.P., Sze S.M., National Chiao Tung University, TW

To study a spin dependence of the electron energy states in tree dimensional cylindrical semiconductor dots we consider theoretically the spin-orbit interaction impact on the electron quantum con...nement in the dots. We solve the problem [...]

Parallel Dynamic Load Balancing for Semiconductor Device Simulations on a Linux Cluster

Li Y., Lin S-S., Liu J-L., Lin S-S., Yu S-M., Liu J-L., Chao T-S., Sze S.M., National Chiao Tung University, TW

A parallel dynamic load balancing for 2-D and 3-D semiconductor device simulations is proposed. The hydrodynamic and drift diffusion models are discretized and solved with finite volume (box) and monotone iterative methods. Dynamic load balancing [...]
