  • Gallium-nitride-based light emitting diodes with multiple potential barriers
    Patent number: 9324907
    Abstract: A light emitting diode (LED) includes an active layer having one or more multilayer potential barriers and at least one well layer. Each multilayer potential barrier includes interlacing first and second InAlGaN thin layers. The first and second InAlGaN thin layers have compositions selected with respect to the well layer such that a polarization effect is substantially reduced.
