Abstract

1429895 Electroluminescence TOKYOSHIBAURA ELECTRIC CO Ltd 28 Jan 1974 [12 Feb 1973 9 Nov 1973] 3915/74 Heading C4S [Also in Division H1K] A red light emitting gallium phosphide device comprises an N-type GaP body having a surface layer doped with Te, S or Se with an impurity concentration from 2 x 10<SP>17</SP> to 5À8 x 10<SP>17</SP> cm.<SP>-3</SP> and not being doped with O, and a P-type gallium phosphide layer formed on the surface layer and doped with Zn and O to define a light emitting junction, the concentration of Te, S or Se being higher than that of Zn. Liquid phase epitaxy growth is detailed for apparatus as in Fig. 4 (not shown) including carbon body (11) and horizontally sliding plate (13) containing solution (15) of GaP with N- or P-type impurities, and GaP substrate (17). A temporary Au layer on the N-type layer provides a Schottky barrier whereby donor concentration may be determined by capacitance measurements. Electrodes are In and In-Zn alloy. Layer thicknesses are disclosed. The provision that N d should be greater than N a is discussed and concentrations outside the above range are disclosed. Also other devices with oxygen dopant also in the N-layer and N d >1 x 10<SP>18</SP> cm.<SP>-3</SP> are discussed.
