Abstract
This paper investigates the dominant conduction mechanisms in two bi-layer Ta2 O5 -Al2 O3 structures fabricated by atomic layer deposition and rf sputtering. In depth experimental (electrical and optical) and theoretical analysis have been conducted to demonstrate the dominancy of quantum mechanical tunnelling, a desirable conduction mechanism for high-speed nanorectifier device operation.
