Abstract(in English) | GaN-based HBTs are very promising as next-generation high-frequency power devices. However, when considering the realization of GaN-HBTs, there are several issues such as high offset voltages caused by the high resistance of p-type base layers. In this study, we investigated a p-GaInN base layer, which is expected to have lower resistivity than the p-GaN base layer, and a quaternary AlGaInN emitter layer which allows for the design of energy band gaps with less strains realizing low offset voltages in GaN HBTs. The electrical properties and surface morphologies of p-GaInN grown at 800°C to 840°C by MOCVD were investigated, and p-GaInN with an InN mole fraction of 4% or less was considered promising as a base layer. Nearly lattice-matched quaternary AlGaInN emitter layers were designed and grown by varying InN mole fractions at a constant AlN/GaN mole ratio, so as to satisfy an energy band offset and a surface flatness at the same time. |
