What is best way to calculate optical band gap of nanostructures?
I’m trying to reproduce the acousto-optic coupling simulation in the paper Frequency–angular resolving LiDAR using chip-scale acousto-optic beam steering. LNOI(lithium niobate on insulator) is...

I'm researching light sources and their UV emissions. I'm curious if a 50W, 7500K conventional LED lamp emits any UV light. I found that a 200W tungsten lamp can emit up to 1.5 mW/cm² at 350 nm....
