The effect of the impurity incorporation was investigated by electrical and electron spin resonance measurements. Both O and N impurities were found to increase the dark conductivity by decreasing its activation energy in a‐Si:H films. Furthermore, it was found that O and N impurities delay the photoresponse. C impurity, however, has no appreciable effect on them. These findings suggest that O and N impurities shift the Fermi level upward and form a trapping state for photoexcited electrons, supporting our O+3 and N+4 model., 金沢大学設計製造技術研究所 / 金沢大学理工研究域電子情報学系 / 金沢大学工学部}, pages = {2130--2132}, title = {Doping effect of oxygen or nitorogen impurity in hydrogenated amoorphous silicon films}, volume = {59}, year = {1991} }
