A local-density approximation for the exchange energy functional for excited states : the band gap problem

Moshiour Rahaman, Shreemoyee Ganguly, Prasanjit Samal +3

We present excited states density functional theory (DFT) to calculate band gap for semiconductors and insulators. For the excited states exchange-correlation functional, we use a…
