摘要
Bottom gate type thin film transistors using nano-crystalline GaN (nc-GaN) films were studied. The nc-GaN films were deposited by a reactive sputtering method and were annealed at 800 degrees C after depositions. The grain sizes were 10 to 20 nm by using Scherrer's formula. The threshold voltage (V(th)), the field effect mobility (mu) and the ratio of on-current and off-current (R(on/off)) were -0.4 V, 6 x 10(-2) cm(2)/V s and 3000, respectively. The fabricated nc-GaN TFT was a depletion type. The possibility for applying the nc-GaN film to high temperature operation is shown. (C) 1998 Elsevier Science B.V. All rights reserved.
