Residual acceptor impurities in high purity LPE-GaAs and VPE-GaAs have been investigated by photoluminescence at 4.2K and 1.8K. The experimental results show that residual acceptor impurities are C

system only carbon can be detected as a dominant acceptor impurity. The effect of some growth conditions on incorporation of residual acceptor impurities heve also been studied.
