Current-amplifying transistor device and current-amplifying, light-emitting transistor device

摘要

A current-amplifying transistor device is provided, between an emitter electrode and a collector electrode, with two organic semiconductor layers and a sheet-shaped base electrode. One of the organic semiconductor layers is arranged between the emitter electrode and the base collector electrode, and has a diode structure of a p-type organic semiconductor layer and an n-type p-type organic semiconductor layer. A current-amplifying, light-emitting transistor device including the current-amplifying transistor device and an organic EL device portion formed in the current-amplifying transistor device is also disclosed.
