FIELD: physics.
SUBSTANCE: proposed method comprises pre-cleaning of GaSb p-junction conductance by ion-plasma etching to depth of 5-30 nm with subsequent deposition by magnetron sputtering of adhesion titanium 5-30 nm-thick layer and platinum 20-100 nm-thick barrier layer, evaporating thermally of 50-5000 nm-thick silver layer and 30-200nm-thick gold layer for contact with ambient medium.
EFFECT: reproducible ohmic contact with low specific junction resistance.
