Abstract:
1. A bipolar junction transistor comprising: a doped inorganic semiconductor layer; an emitter electrode; a base electrode; a collector electrode; a first structure operatively associated with the emitter electrode for transporting charge carriers having a first charge type into the inorganic semiconductor layer and suppressing diffusion of charge carriers having a second charge type opposite from the first charge type from the inorganic semiconductor layer, the first structure being positioned between the emitter electrode and the inorganic semiconductor layer and including a first organic semiconductor carrier transport layer for transporting the charge carriers having the first type; a second structure operatively associated with the base electrode for transporting charge carriers having the second charge type into the inorganic semiconductor layer and suppressing diffusion of charge carriers having the first charge type from the inorganic semiconductor layer, the second structure being positioned between the base electrode and the inorganic semiconductor layer, and a third structure operatively associated with the collector electrode for transporting charge carriers having the first charge type into the inorganic semiconductor layer and suppressing diffusion of charge carriers having the second charge type from the inorganic semiconductor layer, the third structure being positioned between the collector electrode and the inorganic semiconductor layer.
