  • Abstract
    GeMoW is presented as a refractory ohmic contact to n-type GaAs with an In0.5Ga0.5As cap layer. The contact exhibits ohmic behaviour over a wide annealing temperature range from 300 to 700 degrees C. A minimum contact resistance of 0.176 Omega mm was obtained following furnace annealing at 500 degrees C.
