Summary

Nitride-SRH was a European Horizon 2020 project under the Marie-Sklodowska Curie Actions (project No. 657054). The project was conducted by dr. Audrius Alkauskas from May 2015 to January 2017. The major goal of the project is to identify defects that cause nonradiative (the so-called Shockley-Read-Hall) recombination in nitride light-emitting diodes.

Software

The project is resulted in the following Fortran codes:

1. Luminescence lineshapes within 1D approximation: 1D_vib_lineshapes.tar.gz
README file could be found here.

2. Nonradiative capture rate within the 1D approximation: nonrad.F90
README file could be found here.

The programs are still being developed.
