A systematic study of the role of the insulator layer on rectification performance in metal-insulator-metal structures is reported. Four different MIM systems with Nb/Pt metal pairs and Nb2O5, TiO2, Al2O3, MgO as the insulator candidates are investigated based on an empirical hypothesis. As per the hypothesis and experimental verification, several prospective MIM systems such as Sm/ZrO2/Pt and Hf/TiO2/Pt are identified and a MIM materials-space is constructed.
