Abstract

Abstract: Additional electric field (AEF) in the Schottky contacts (SC) that covered the peripheral contact region wide and the complete contact region narrow (as TMBS diode) SC. Under the influence of AEF is a redistribution of free electrons produced at certain temperatures of the semiconductor, and is formed the space charge region (SCR). As a result of the superposition of the electric fields SCR and AEF occurs the resulting electric field (REF). The REF is distributed along a straight line perpendicular to the contact surface, so that its intensity (and potential) has a minimum value on the metal surface and the maximum value at a great distance from the metal surface deep into the SCR. Under the influence of AEF as a sided force the metal becomes negative pole and semiconductor - positive pole, therefore, SC with AEF becomes an alternative current source (ACS). The Ni-nSi SC with different diameters (20–1000 μm) under the influence of the AEF as sided force have become ACS with electromotive force in the order of 0.1–1.0 mV, which are generated the electric current in the range of 10-9–10-7 A, flowing through the external resistance 1000 Ohm. Highlights: Under the influence of additional electric field is formed resulting electric field in Schottky contact. Additional electric field in Schottky contact is as sided force in current source. Schottky contact with additional electric field becomes an alternative current source.
