Resistivity of boron doped diamond

In this Letter, we present a significant advance in boron-doped diamond material synthesis, with film resistivities reduced by almost two orders of magnitude with respect to the de reference data of the field for boron concentrations in the range from 1 x 10(18) to 3 x 10(19) cm. The study is conducted on a series of boron-doped diamond homoepitaxial layers rei grown using the microwave plasma assisted vapour phase epitaxy. The electrical properties were obtained from Hall effect measurements and conductivity data probed in the vander Paw configuration at room temperature. The work highlights the important progress made on diamond material synthesis over the last decade, with significant advances in the reduction of compensation effects.
