Product

WIAS-TeSCA (Two- and three-dimensional semiconductor analysis package) is a program system for the numerical simulation of charge transfer processes in semiconductor structures, especially also in semiconductor lasers. It is based on the drift-diffusion model and considers a multitude of additional physical effects, like optical radiation, temperature influences and the kinetics of deep (trapped) impurities. Its efficiency is based on the analytic study of the strongly nonlinear system of partial differential equations (van Roosbroeck), which describes the electron and hole currents. Very efficient numerical procedures for both the stationary and transient simulation have been implemented in WIAS-TeSCA.

Fields of Application

WIAS-TeSCA has been successfully used in the research and industrial development of new electronic and optoelectronic semiconductor devices such as transistors, diodes, sensors, detectors and lasers and has already proved its worth many times in the planning and optimization of these devices. WIAS-TeSCA covers a broad spectrum of applications, from hetero-bipolar transistor (mobile telephone systems, computer networks) through high-voltage transistors (power electronics) and semiconductor laser diodes (fiber optic communication systems, medical technology) to radiation detectors (space research, high energy physics).

Key Features

Key Benefits

WIAS-TeSCA is an efficient simulation tool for analyzing and designing modern semiconductor devices with a broad range of performance that has proved successful in solving many practical problems. Particularly, it offers the possibility to calculate self-consistently the interplay of electronic, optical and thermic effects. WIAS-TeSCA stands out for its high flexibility. It is used especially for problems where expensive and time consuming experiments and conventional simulation software find their limits.
