Treffer: KdotPsoft: Modelling and Simulation of Semiconductors and Device Physics.

We introduce a new platform called KdotPsoft, to model and simulate semiconductor quantum wells (QWs) and multiple QW (MQW) systems. It is suitable to design and study quantum cascaded lasers, vertical-cavity surface-emitting laser, etc in conjunction with experiment and fabrication. For fundamental physics and device physics applications, KdotPsoft is an ideal platform to model, simulate and study semiconductors QWs and MQW structures for fundamental physics and device physics applications. It can study MQW based structures such as quantum cascaded lasers (QCL), vertical-cavity surface-emitting laser (VCSEL), etc. KdotPsoft is based on the 16-band k·p perturbation theory model and it supports all conventional semiconductor materials, and also can works for dilute nitride and bismide doped semiconductors. As a demonstration, we will show a study an example case of lattice matched GaNBiAs/GaAs QWs and show its major results, such as the energy dispersion curves, optical gain spectra and electron-hole wave-functions. At a larger scale, it can be used to comprehensively study the band lineups, energy dispersion relation, DOS, polarization-dependent transition matrix element strengths, optical gain/absorption spectra, spontaneous emission rate, radiative current density, electric field effects on the QW, etc. Advanced users may note that the development of the platform was done using Fortran and Python. We will strive to make KdotPsoft available as a independent platform or a Matlab toolbox in the future. [ABSTRACT FROM AUTHOR]
