Photon emission gain in Er doped Si light emitting diodes by impact excitation
Huayou Liu, Jiayuan Zhao, Jing Zhang +6
This work demonstrates photon emission gain, i.e., emission of multiple photons per injected electron, through impact excitation in Er-doped silicon light-emitting diodes (LEDs). C…
