Abstract :
The effects of other physical properties on the electrical and optical properties of the double-heterostructure optoelectronic switch device are calculated. The device is similar to an earlier version, but the charge sheet responsible for the unique electrical and optical switching properties of the device is placed in the wide-bandgap barrier layer rather than in the narrow-bandgap active layer. This generally improves the overall operating characteristics of the device because in principle it allows higher charge sheet doping values. This is possible because the charge sheet remains ionized even for very high inversion channel densities
