Low frequencies anomalies in GaAs FETs

Iqbal M.A., University of the Punjab, PK

The activation energy and capture cross section of the traps founds in GaAs field Effect transistors (GaAs FETS) have been measured both in ohmic and saturation region. A variety of transients found using frequency dispersion, [...]

The Effects of gamma-ray Radiation on n-channel MOSFET

Iqbal M.A., University of the Punjab, PK

The response of an n-channel MOSFET to different energy gamma-ray irradiation is investigated as a function of dose rate. The radiation deposits energy by causing ionization in the oxide layer of the device. The ionization [...]
