摘要

This paper reports the post-growth annealing effects of low-temperature grown Mg-doped InGaN. By using MOVPE, 1 mm-thick Mg-doped InxGa1-xN (x similar to 0.36) films are grown at 570 degrees C. In order to activate the Mg acceptors, grown samples are treated by the conventional furnace annealing (FA) or the rapid thermal annealing (RTA). In the case of the FA at 650 degrees C for 20 min, the InGaN film is phase-separated. On the other hand, the RTA at a temperature higher than 700 degrees C enables us to get p-type samples. By using the RTA at 850 for 20 s, p-type samples with a hole concentration 10(18) - 10(19) cm(-3) are successfully obtained without phase separation. (C) 2015 WILEY-VCH Verlag GmbH & Co.
