The nextnano.NEGF software has been developed to simulate electron dynamics in heterostructures like superlattices and **quantum cascade lasers** (QCLs). It can also be used to simulate absorption spectra in quantum wells (QWs) and transport in **resonant tunneling diodes** (RTDs). | The nextnano.NEGF software has been developed to simulate electron dynamics in heterostructures like superlattices and **quantum cascade lasers** (QCLs).
