Web(indium aluminum arsenide, InAlAs). Therefore, InP-HEMTs are characterized by high electron mobility, high electron saturation velocity, and high electron concentration. To enhance the high-speed and low-noise characteristics of HEMTs, it is necessary to increase the electorn mobility in the channel. WebThe InAlAs material is an electron multiplication material with a k-ratio of 0.29–0.5 [7], while InP is a hole multiplication material with a k-ratio of 0.4–0.5 [8]. Moreover, an APD with InAlAs multiplication layer has better stability compared with the one based on InP multiplication layer [3].
