A novel Silicon-Nitride based Light-Emitting Transistor (SiNLET) is proposed for the first time. This three-terminal electroluminescence device uses a SONOS-type device structure, and its process is compatible to standard CMOS devices. Photons are generated by Fowler-Nordheim electron (FN-E) tunnel-injection, band-to-band tunneling induced hot-hole (BTBT-HH) injection, and carrier scattering/trapping/recombination via nitride traps. SiNLET with an effective device area of 0.616 μm
is demonstrated for display and optical communication purposes.
