  • Abstract
    TiPtAu/p-InGaAsP ohmic contacts for laser devices show nonohmic behaviour which is attributed to damage induced by plasma processes during fabrication. Surface recovering by chemical etching of the top few tenths of a nanometre enables ohmic contacts to be obtained. These results were confirmed using SPICE simulations.
