Abstract
<PICT:1072550/C4-C5/1> A semi-conductor device comprises an electrically insulating substrate and a layer of semi-conductor material including a PN junction divided into two mutually insulated regions by a groove extending across the junction, one of the regions being operatable as a radiation emissive diode and the other as a photo-sensitive diode, said groove being filled with a material which reduces loss of radiation by reflection. N-doped GaAs 2 is deposited epitaxially on a highly resistive substrate of Cr-doped GaAs 1. Zn is diffused in to give a PN junction 3. A groove 4 is formed by etching with sodium hypochlorite through a fissure in an SiO2 mask, thus giving two mutually insulated regions 19 and 20 to which ohmic contacts 5, 6, 7 and 8 are added. The groove 4 may be filled with Se or SiO2 whilst the outer surfaces of the device may be covered, 9, with gold. Two other embodiments are described, one (Fig. 2, not shown) has an inset PN junction whilst the other (Fig. 3, not shown) has a curved groove to give two almost circular PN junctions. The emissive diode is said to emit light of 9000 <\>rA.
