Abstract
A method for making electrical contacts to diamond, in which a surface layer of the diamond is transformed by means of a laser beam into graphite having a sheet resistivity in the range of 5 to 100 Ohms. The diamond to be treated and the laser beam are moved with respect to each other according to a raster pattern. The laser is operated with such a pulse width and pulse frequency, the laser beam is focussed in such a way and is moved with respect to the diamond at such a speed, that pit-like surface areas of graphite are formed which join or overlap. After the graphitization a wire or other electrical conductor is fixed to the graphite layer, through which a diamond having electrical contacts is obtained.
