A Review of Research on Devices Using nc-Si:H Film

Research advances in electronic devices and photoelectricity transition devices such as tunneling diode, heterojunction diode, varied capacitance diode, single electronic transistor, solar cell and light emitting diode(LED)using hydrogenated nano-crystalline silicon(nc-Si:H)films are reviewed in this paper. The relation ship between the performance of these devices and the structures of nc-Si:H films is analyzed. The advantages of these novel devices are pointed out.
