TUNABLE WAVELENGTH LIGHT EMITTING DIODE

摘要

A light emitting diode and a method of fabricating a light emitting diode, the diode has a first set of multiple quantum wells (MQWs), each of the MQWs of the first set comprising a wetting layer providing nucleation sites for quantum dots (QDs) or QD-like structures in a well layer of said each MQW; and a second set of MQWs, each of the MQWs of the second set formed so as to exhibit a photoluminescence (PL) peak wavelength shifted compared to the MQWs of the first set.
