摘要:
The effect on the electrical properties, relevant to noise, from the gate-channel distance (barrier layer thickness) in 130 nm gate-length InP HEMTs was investigated. An increased quality of pinch-off was seen in HEMTs with an 8 nm barrier layer thickness compared to an 11 nm barrier. For the 8 nm barrier material the gate leakage increased from 1 mu A/mm to 7 mu A/mm at -1 V gate bias.
