Abstract
A circuit component that exhibits a region of negative differential resistance includes: a first layer of material; and a second layer of material in contact with the first layer of material, the contact forming a first self-heating interface. The first self-heating interface is structured such that an electrical current flowing from the first layer of material to the second layer of material encounters an electrical impedance occurring at the first interface that is greater than any electrical impedance occurring in the first and second layers of material, wherein heating occurring at the first interface is dominated by Joule heating caused by the electrical impedance occurring at the first interface, and wherein the electrical impedance occurring at the first interface decreases with increasing temperature to induce a region of negative differential resistance.
