A conductive diamond surface with highest yet reported sheet conductivity and unsurpassed thermal stability is shown to be due to surface transfer doping of hydrogen terminated diamond by a molybdenum trioxide (MoO 3 ). Surface conductivities, as determined by Hall Effect measurements as function of temperature for different MoO 3 thicknesses, have yielded total areal hole densities ranging from 7 × 10 13 cm −2 to 1 × 10 14 cm −2 , exceeding those reported for H 2 O transfer doped diamond.
