Abstract

We studied doping Se into AlGaAs layers using PbSe as a dopant source for molecular beam epitaxy (MBE). Good controllability and abruptness equivalent to that of Si-doping were obtained. Se-doping was successfully applied to HEMT structures with reduced DX center concentrations. The two dimensional electron gas (2DEG) characteristics of these structures were comparable to those of Si-doped structures.
