Özet

The electrical end optical characteristics of InAs/InAs0.7Sb0.1P0.2 heterojunctions were studied. The dark current mechanisms in the heterostructures were investigated at several temperatures. The experimental results shows that, the low temperature region the tunneling mechanism of the current flow dominates in both, forward and reverse biases. At high temperatures region and in the range of voltage from 0.1 V to 1 V. the reverse current was defined by diffusion mechanism. (C) 2011 Elsevier B.V. All rights reserved.
