Abstract:
1. A method for modifying the capacitance, leakage current, and/or flat band voltage of a metal-insulator-semiconductor structure via a change in the work function of the metal, contacting a layer having an OH-terminated oxide surface with a solution comprising organic molecules having a permanent dipolar moment and selected from the group consisting of aminopropyltriethoxysilane, fatty acids, organosilicon derivatives, organosulfur compounds, alkyl chains, diphosphates, and combinations thereof, for a predetermined period of time to form a self-assembled organic layer over the OH-terminated oxide surface; and forming a further layer comprising metal over the self-assembled organic layer to form a metal-insulator-semiconductor structure having a capacitance, a leakage current, and a flat band voltage, wherein the capacitance, the flat band voltage, or the leakage current is modified by selection of the predetermined period of time or by selection of the magnitude or the direction of the permanent dipolar moment of the organic molecules.
