Tantalum Oxide Film

In this work has been developed a technology for obtaining nickel-insulator-aluminum structure with 7 nm thick tantalum oxide deposited by atomic-layer deposition. An asymmetric current-voltage characteristic of the structure is obtained, and the heights of potential barriers at the metal-insulator interface are determined. The permittivity of the tantalum oxide film has been determined experimentally in this work.

Vacuum Gap

High-resolution electron energy distribution measurements of individual microscopic sites have been used to develop a detailed theoretical model of the field-induced hot-electron emission mechanism responsible for pre-breakdown currents at vacuum-gap fields of 10-30 MV m -1 . The model, which is based on the formation of conducting channels in a metal-insulator-vacuum (m. i. v.) micro-emission régime, has provided experimentally verified quantitative relations for the current-voltage characteristic, spectral shape, and the field-dependence of the spectral full width at half maximum (f. w. h. m.) and shift.
