Abstract

1,218,544. Gallium arsenide. MULLARD Ltd. 22 March, 1968 [1 April, 1967], No. 15021/67. Heading C1A. [Also in Divisions B1 and G3] A single crystal of GaAs is produced by passage of a liquid GaAs-containing boat 15, within a scaled tube 14 itself within a conveying tube 3, through a decreasing temperature gradient in a furnace 1 in which point 13 is maintained at the crystallization temperature, crystallization taking place in an atmosphere of As produced by vaporization from a body 16 maintained at a constant temperature (610‹ C.) by means of a variable heating furnace 2. Furnaces 1 and 2 may be thermally isolated. The GaAs is produced by reaction of As vapour with an initial Ga charge.
