Abstract :
This presentation describes on-wafer characterization of GaAsSb/InAlAs/InGaAs tunnel diodes for direct detection in 220-330GHz band. Voltage sensitivity above 1000V/W was measured in 0.8μm×0.8μm mesa device at room temperature. The detectors demonstrated enhanced temperature stability of the characteristics compared to zero-bias Schottky barrier diodes. The estimated variations of the zero-bias sensitivity at temperatures from 17K to 300K were less than 2dB.
