Abstract
We have found that the electrical properties of carriers across the me tal-semiconductor interface for alloyed Zn based metallizations to n- and p-InP are dominated by nanosized non-barrier inhomogeneities. The effective area covered by the nanosized regions is a small fraction of the contact area resulting in high values of the specific contact res istance to p-InP. For n(-)-InP, thermionic emission across nanosized i nhomogeneities dominates the carrier flow when T-ann > 440 degrees C. (C) 1998 Elsevier Science B.V.
