On the angular dependence of InP high electron mobility transistors for cryogenic low noise amplifiers in a magnetic field

AIP Advances, 2019
The InGaAs-InAlAs-InP high electron mobility transistor (InP HEMT) is the preferred active device used in a cryogenic low noise amplifier (LNA) for sensitive detection of microwave signals. We have investigated the angular dependence of the InP HEMT when
