One of the research objectives our group is currently pursuing is to calculate the linear and non-linear optical response of certain low-dimensional semiconductor materials in external electro-magnetic fields. The optical response is important if such materials are to be used in opto-electronic devices such as photo-detectors or light-emitting diodes.
We use a number of numerical methods to calculate the band structure and the optical response of these semiconductor materials, including DFT calculations from software packages such as ABINIT and also our own code. Calculating the band-structures and optical response of materials in external fields is often computationally demanding but can parallelized and is highly suited for the use of HPCs.
