| 摘 要： | A heterojunction diode has been fabricated by boron-doped p-type diamond thin film grown epitaxially on a silicon-doped n-type cubic boron nitride bulk crystal using the conventional hot filament chemical vapour deposition method.The ohmic electrode of Ti(50nm)/Mo(100nm)/Au(300nm)for the p-type diamond film and the bulk crystal of the c-BN were deposited by the rf planar magnetron method.Then the device was annealed at 410℃ in air for 1h in order to form ohmic metal alloy,The current-voltage characteristics of the heterojunction diode were measured and the result indicated that the rectification ratio reached 10^5,and the turn-on voltage and the highest current were 7V and 0.36mA,respectively.
