Abstract
Abstract A radiant diode assembly s provided with a thermally conductive, electrically nonconductive submount, in combination with a metallic heat sink mounting member, thereby permitting series interconnection of the individual units of a multipl1Diode array. Gold-doped silicon is the preferred submount, having a gold content of about 1016 atoms per cm.3 , a thermal conductviity of about 6 watts per cm. per o k., and an electrical resistivity of about 20,000 ohm-cm. at an operating temperature of about 80*K. to 120*K.
