Abstract :
In this paper we review ultrafast optoelectronics devices made from low-temperature grown GaAs and related materials. The required material parameters for optimized devices are discussed. Our investigations on technology, structural quality, electrical characteristics and photoexcited carrier dynamics show that beryllium doped LT-GaAs meets all these requirements. In addition, doping with Be provides more flexibility in tuning material characteristics of low-temperature grown GaAs, which is a considerable advantage in device fabrication
