semiconductor device having metallic nanodroplet for enhancement of photoemission in off-resonant plasmon

摘要

The present invention provides a semiconductor device having an improved photoelectron emission property by using an electrostatic force of Coulomb in an off-resonant plasmon. According to an embodiment of the present invention, the semiconductor device having a metal nano-droplet for enhancement of a photoelectron emission property in an off-resonant plasmon has an active layer including metal nano-droplets separated in an island form on the upper part of a GaAs/AlGaAs quantum well layer.
