제목 Characteristics of p- and n-type SnO thin films fabricated by reactive sputtering
초록 SnO thin films were fabricated via reactive rf magnetron sputtering on glass substrates with an Sn target and Ar/O2 gas mixture. The n-type to p-type conductivity inversion of SnO thin films was demonstrated by increasing rf power. The electrical conductivity of SnO thin films showed a relatively low p-type conductivity of 0.05 (ohm-cm)−1 due to a low mobility. Consequently, it showed very poor p-channel characteristics. SnO thin films consisted of a short-range ordered cryatalline phase and the degree of crystallinity was improved as rf power increased. Lastly, SnO thin films had poor optical transmittance in the visible range at a higher rf power.
