Abstract
The effects of low temperature on the characteristics of 0.35 μm gate-length AlSb/InAs HEMTS are reported. Measurements down to 15 K reveal an increase in transconductance and low-field source-drain conductance. The commonly-observed impact ionisation and its associated gate current were found to decrease significally at low temperature apparently due to a increase in bandgap
