Electrical Properties of Boron-Implanted Homoepitaxial Diamond Films

Abstract
Electrical properties produced by boron implantation in homoepitaxial diamond films grown by chemical vapour deposition (CVD) have been studied. Two techniques were employed to anneal out implantation damage: thermal annealing and hydrogen plasma treatment. A large difference in electrical properties between boron-implanted CVD and high-pressure synthesized (HPS) diamonds after thermal annealing has been observed. Hydrogen plasma treatment has a substantial advantage concerning the electrical properties of implanted diamond compared with thermal annealing.
