Abstract

A high growth rate process has been used to grow thin homoepitaxial diamond layers on type Ib single crystal substrates. The layers are p-type due to the presence of surface adsorbed hydrogen. STM measurements confirm a highly smooth surface (<1.5 nm Ra) and Hall effect measurements indicate very high mobility values within the p-type layer at sheet carrier concentrations that are high enough to be useful for device applications (140 cm2 V−1 s−1 @ 2.5×1012 cm−2).
