Density functional theory is used to show that charge transfer occurs between chemical dopants in GaAs and adsorbates composed of C-60 and graphene lying on the (110) surface of GaAs. In the case of C-60, charge transfer only occurs for n-type GaAs in agreement with previous experimental results. However, the calculations show that transfer between graphene and both n- and p-type GaAs can occur which offers a simple way of doping graphene.
