  • Abstract
    We present a detailed investigation of the electrically active Rh concentration in low-pressure metalorganic chemical vapor-phase epitaxy grown InP:Rh in dependence of the growth parameters. Rh introduces two deep mid gap acceptor levels RhA and RhB in InP at Ev+0.71 eV and Ev+0.62 eV, respectively. Taking into account the low diffusivity of Rh in InP (Drh(800°C)⩽1×1014 cm2/s) Rh is an interesting candidate as compensating dopant for thermally stable semi-insulating InP. We show that the electrically active Rh concentration can be increased by a factor 5 using the inert carrier gas N2 instead of H2
