Semi-insulating chromium-doped GaAs epitaxial layers were grown using a Ga/AsCl 3 /H 2 system with CrO 2 Cl 2 as a dopant. The resistivity was of the order of 10 8 ohm cm. It was shown that chromium acted as deep acceptor with an activation energy of 0.57 eV and could compensate shallow donors with a concentration of about 10 16 cm -3 . The n-type layer doped with sulfur whose carrier concentration was 1.2 x 10 17 cm -3 with a mobility of 5200 cm 2 /V sec was successively grown on the semi-insulating epitaxial layer in one run. The boundary layer was abrupt and excellent for FET application.
