GW for band gap calculations?
Closed | Responses: 0
I am new to nanoHUB, so please forgive my ignorance. I am fascinated with it by the way!!!. I have briefly followed some tutorials. I am particularly interested in the band...
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...
How to calculate the bandgap of a nano sized mixed metal oxide?
Silicon-Germanium HBT simulation
Are there any tools to simulate SiGe HBT devices? The tools must that can also simulate the irradiation effects...

Best method to calculate Phosphorene band gap apart from HSE06.
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...
