ABSTRACT:
A solution of a hydrazine-based precursor of a metal chalcogenide is prepared by adding an elemental metal and an elemental chalcogen to a hydrazine compound. The precursor solution can be used to form a film. The precursor solutions can be used in preparing field-effect transistors, photovoltaic devices and phase-change memory devices.
