abstract = {A new mechanism of contact resistance formation in ohmic
contacts with high dislocation density is proposed. Its
specific feature is the appearance of a characteristic
region where the contact resistance increases with
temperature. According to the mechanism revealed, the
current flowing through the metal shunts associated with
dislocations is determined by electron diffusion. It is
shown that current flows through the semiconductor
near-surface regions where electrons accumulate. A feature
of the mechanism is the realization of ohmic contact
irrespective of the relation between the contact and bulk
resistances. The theory is proved for contacts formed to
III-V semiconductor materials as well as silicon-based
materials. A reasonable agreement between theory and
experimental results is obtained. (C) 2012 American
