Some electrical-contact effects that occur when a conical indenter is pressed into a flat anvil through a thin layer of dielectric material
Stishov S. M., Kachinskii V. N.
It is shown that the electrical effects observed during the compression of a thin dielectric layer in a system comprised of a conical indenter and a flat anvil can be described as the result of a reversible short circuit without invoking the hypothesis of a metal-dielectric junction.
