Contact force or pressure increases the size of the a-spot which decreases the constriction resistance and the electrical contact resistance. [11] When the size of contacting asperities becomes larger than the mean free path of electrons, Holm-type contacts become the dominant transport mechanism, resulting in a relatively low contact ...
A contact can be formed during deposition, by the intrusion of magma, [2] or through faulting or other deformation of rock beds that brings distinct rock bodies into contact. [ 3 ] The geologic subdiscipline of stratigraphy is primarily concerned with depositional contacts, [ 4 ] while faults and shear zones are of particular interest in ...
