NANOWIRE-BASED OPTOELECTRONIC DEVICE FOR LIGHT EMISSION

摘要

A light-emitting diode is provided, including an active semiconductor area for the radiative recombination of electron-hole pairs having a plurality of nanowires, each made of an unintentionally doped semiconductor material, a first semiconductor area for radially injecting holes into each nanowire, the first semiconductor area being made of a doped semiconductor material having a first conductivity type and having a bandgap that is greater than the bandgap of the semiconductor material of the nanowires, and a second semiconductor area for axially injecting electrons into each nanowire, the second semiconductor area being made of a doped semiconductor material having a second conductivity type that is opposite to that of the first conductivity type.
