Abstract:
A method of preparing a diamond semiconductor by irradiating with a corpuscular ray a diamond substrate or a thin film of diamond deposited on a substrate material, comprising:maintaining said diamond substrate or said thin film of diamond at a temperature of 300Â° C. to 2000Â° C. when applying said corpuscular ray; setting an angle of a surface of said diamond substrate or said thin film of diamond irradiated with said corpuscular ray within the range of âˆ’20Â° to +20Â° to the (001) crystal plane of said diamond substrate or said thin film of diamond; and setting an angle of the direction of said corpuscular ray within the range of âˆ’20Â° to +20Â° to the <001> crystal orientation of said diamond substrate or said thin film of diamond.
