Abstract
We report the realization of an ultraviolet Light-emitting diode with the u se of a diamond pn junction. The pn junction was formed from a boron-doped p-type diamond Layer and phosphorus-doped n-type diamond Layer grown epitax ially on the {111} surface of single crystalline diamond. The pn junction e xhibited good diode characteristics, and at forward bias of about 20 volts strong ultraviolet Light emission at 235 nanometers was observed and was at tributed to free exciton recombination.
