摘要
AlGaN/GaN double heterostructure high electron mobility transistor (DH-HEMT's) with a 2.0 mu m gate length and a 4 mu m channel length exhibiting good temperature characteristics has been demonstrated. The maximum drain current I-ds and extrinsic transconductance G(m) are 1300mA/mm 235mS/mm, 850mA/mm 174mS/mm and 475mA/mm 95mS/rnm, respectively at T = 194 degrees C, 20 degrees C and 400 degrees C. The temperature coefficient of I-ds and G are -1.4mA/degrees C and -0.24mS/degrees C respectively.
