Abstract

The present paper examines the influence of ion type Nitrogen and Argon on the transportation through the structures. The interfaces of structures have been created through the ion implantation process. The interfaces consist of Tantalum layers that undergo bombardment by Argon and Nitrogen ions. The energy of the ion has been taken into account at 30 keV. The outcomes have been obtained at varying doses under room temperature conditions.

In order to study the morphology of the ion implanted rough thin films, the Atomic Force Microscopy analysis applied. The average value of roughness calculated. Reducing the transmission probability is the main result of the structures rough interfaces. The obtained results illustrate that the produced interfaces by Argon ion implantation, were rougher than Nitrogen ones. Moreover in both two cases, the peak to valley ratio reduces. Additionally, as the dose of Nitrogen ion increases, the current density decreases as a function of voltage
