In one aspect, a method includes forming an electrical path between p-type mercury cadmium telluride and a metal layer. The forming of the electrical path includes depositing a layer of polycrystalline p-type silicon directly on to the p-type mercury cadmium telluride and forming the metal layer on the layer of polycrystalline p-type silicon. In another aspect, an apparatus includes an electrical path. The electrical path includes a p-type mercury cadmium telluride layer, a polycrystalline p-type silicon layer in direct contact with the p-type mercury cadmium telluride layer, a metal silicide in direct contact with the polycrystalline p-type silicon layer, and an electrically conductive metal on the metal silicide. In operation, holes, indicative of electrical current on the electrical path, flow from the p-type mercury cadmium telluride layer to the electrically conductive metal.
