Abstract

<PICT:1016464/C4-C5/1> In a semi-conductor device in which emission, of radiation is stimulated by charge carrier injection at a P-N junction in a semi-conductor crystal, the crystal is a mixed crystal composed of at least two semi-conductor substances in such proportions that the energy maximum in the valence band occurs at the same value of wave number vector as the energy minimum in the conduction band. The crystal may be employed in an electroluminescent lamp or as a laser or maser. In the lamp illustrated the crystal 2 is mounted in the platinum plate 3 which also carries a lens 8, and a ceramic spacer 4 carries a metal plate 5 with a lead 6 to the alloying pill 7; the crystal is of gallium phosphide and gallium arsenide, less than 10 m thick, and the pill an indium-zinc alloy. Other crystal components mentioned are gallium antimonide, indium phosphide, arsenide and antimonide, and aluminium phosphide, while silicon, tin, sulphur, selenium or tellurium may be used as doping agents.
