Franz–Keldysh effect

Known as: Franz-Keldysh effect, Franz-Keldysh effect and modulation spectroscopy, Franz–Keldysh effect and modulation spectroscopy 
The Franz–Keldysh effect is a change in optical absorption by a semiconductor when an electric field is applied. The effect is named after the German… (More)
