摘要
The current-voltage (I-V) measurements on Pt/InN Schottky barrier diodes in the temperature range 10-280 K were done. It was found that the contact was Schottky up to 280 K, becoming irreversible ohmic for higher temperatures. The ideality factors were calculated using the Cheung method. The measurements were best explained using the tunnelling model. A value of m(perpendicular to)* = 0.237 m(0) is obtained. (C) 2009 The Japan Society of Applied Physics DOI: 10.1143/JJAP.48.070201
