Abstract
A method of reducing the specific contact resistivity of a metal to semiconductor interface between a metal contact and an InP semiconductor compound. The method includes the step of increasing the amount of the group V element (P) in the semiconductor compound so that the semiconductor compound is non-stoichiometric having an excess concentration of the group V element in an amount of at least 0.1% above stoichiometric levels.
