ABSTRACT:
In an npn-type transistor, the emitter42and the collector43are formed of an n-type transparent semiconductor, and the base41is formed by a p-type transparent semiconductor. The base electrode44, the emitter electrode45and the collector electrode46are formed respectively on the base41, the emitter42and the collector43. As the n-type transparent semiconductor, for example, n-type ZnO is used. The n-type ZnO is ZnO doped with, for example, group III elements, group VII elements. As the p-type transparent semiconductor, for example, p-type ZnO is used. The p-type ZnO is ZnO doped with, for example, group I elements and group V elements.
