Software lab for semiconductor device characterization

We have developed a software system for obtaining physical and electrical concepts of semiconductor devices and named it `SLSD´ (Software Lab for Semiconductor Devices). This work has been based on the following points: 1) use of new formulas for finite differentiation; 2) use of a matrix form for differentiation operators in differential equations. By virtue of these, we can organize the software system as a software lab; that is, a collection of small discrete programs that can used by students together to do desired simulations. The two main transport models, classical model based on Shockley-Reid equations and semiclassical model based on Boltzmann equation as well as a Schrodinger equation solver and a Laplace solver have been installed in this lab. One can do many different experiments in this lab. These experiments cover a wide range of interesting matters in the field. We briefly explain six topical experiments in this paper
