Research Abstract |
The objective of this research is to develop a novel current injection in wide bandgap semiconductors, especially nitride semiconductors which are supreme materials for light emitting and detecting devices covering the ranges from infrared to deep ultraviolet. Such wide bandgap materials show highly resistive p-layers, resulting in poor characteristics of ultraviolet light emitting devices. In the research very low resistive tunnel junctions have been obtained. The highly resistive p-layers are replaced with the low resistive n-layers by the tunnel junctions, leading to novel light emitting and detecting devices. High In content GaInN tunnel junctions show one order of magnitude lower resistances than before. Current confinement micro light emitting diodes, micro displays and tandem solar cells have been developed with the tunnel junctions. The novel current injection with tunnel junctions has been established.
