  • Abstract
    This paper investigates the dominant conduction mechanisms in two bi-layer Ta2O5-Al2O3 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.
