Abstract
The electrical properties of Ga1−X InXAsYSb1−Y (X=0.14–0.27) solid solutions grown from a Pb-containing solution-melt were investigated for the first time. Three acceptor levels were found to exist, specifically, a shallow level with the activation energy E A1≈0.008–0.015 eV, and two deep levels E A2≈0.024–0.033 eV and E A3≈0.07 eV. It is demonstrated that the use of Pb makes it possible to obtain undoped solid solutions with a low concentration of defects and impurities and with high carrier mobility.
