Abstract

1,247,437. Electroluminescence. NATIONAL RESEARCH DEVELOPMENT CORP. 2 March, 1970 [8 March, 1969], No. 12353/69. Heading C4S. [Also in Division H1] A GaP electroluminescent diode is produced by depositing an N-type layer followed by a P-type layer containing a deep level impurity on a substrate both layers being formed by liquid phasee pitaxy (solution growth). A slice is cut from a liquid encapsulated pulled crystal of N-type GaP doped with S or Te, lapped and etched and mounted on a quartz "spade" with the phosphorus (111) face exposed. It is then vertically dipped into a molten solution of GaP in Ga doped with Te which is allowed to cool to deposit as N-type epitaxial layer on the surface. Excess Ga is removed by scraping and dissolution and the surface cleaned by etching. The slice is then placed in a horizontal capsule together with the components of a solution which comprise Ga, GaP, ZnO and Ga 2 O 3 . The capsule is flushed with forming gas and closed by means of a plug. The capsule is heated to melt the solution and then tilted to flood the solution over the wafer and then allowed to cool to deposit a P-type epitaxial layer containing Zn as the accepter and O as a deep level impurity on top of the N-type epitaxial layer. The excess Ga is again removed, the slice is sawn or cleft into dice and ohmic contacts of Au 2% Sn and Au 2% Zn are applied to the N-type substrate and P-type layer respectively. The donor impurities may be S, Te, Se, Sn or Si and the accepter impurities may be Zn or Cd.
