摘要: Polarization-charge tunnel junctions for ultraviolet light-emitters (λ<360 nm) are modeled using the k⋅p multiband quantum transmitting boundary method. It is shown that polarization-charge can carry sufficient current to be viable emitters. Sources of inefficiency in existing emitters discussed, including poor hole-injection efficiency and optical absorption p-type GaN contact layers. demonstrated deliver improvements both areas, by eliminating need contacts, enabling use a p-side-down structure, which have favorable characteristics carrier transport compared conventional p-side-up structures.
