4. nextnano.NEGF

nextnano.NEGF is a tool designed for accurate quantum simulations of semiconducting devices using the Non-Equilibrium Green Functions (NEGF) formalism. It has been originally developed to simulate electron dynamics and gain in quantum cascade lasers (QCLs) and superlattices. It can also be apply to infrared detectors such as quantum well infrared detectors (QWIPs) and quantum cascade detectors (QCDs), as well as transport in resonant tunneling diodes (RTDs). It is progressively extended to further applications such as interband devices.
