Best method to calculate Phosphorene band gap apart from HSE06.
Closed | Responses: 0
We know that DFT-GGA underestimates the Phosphorene band gap. HSE06 gives better result. Is there any other computational method apart from HSE06, which gives good result which is very...

How much heat energy will be released, if any, while an excited electron relaxes into the valence band in a direct band-gap material?
Open | Responses: 1
When electrons of a direct band-gap material are excited by photons (from laser source) from conduction to valence band, how much are energy will be emitted in the form of heat during its...
