Low frequencies anomalies in GaAs FETs


Keywords: , , , ,

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, generation recombination noise techniques and DLTS techniques. The measure properties indicate that thermal emission from these traps is not a simple exponential. The transient differ from one trap to another and the location of each traps are influenced by the device structure.
