Abstract : To develop a solid-state light source, first studied was the mechanism of the existing electroliminescence of zinc sulfide powder, which was found to be based on bipolar alternating injection of electrons and holes from conducting, copper-decorated imperfection lines, and recombination at field reversal. To extend this principle to efficient dc operation, the technology was developed of crystal growth liminescent, conducting II-VI compounds from the melt under pressure, and injection mechanisms were found active in resulting broad p-i-n heterojunctions. A new type of injecting heterojunction, based on tunneling through thin insulating films, was invented, permitting minority carrier injection into luminescent semiconductors regardless of compensation.
