Provided herein are methods of performing liquid phase epitaxy (LPE) of III-V compounds and alloys at low pressures using pulsed nitrogen plasma to form an epitaxial layer e.g. on a substrate. The pulse sequence of plasma (with on and off time scales) enables LPE but avoids crust formation on top of molten metal. The concentration of nitrogen inside the molten metal is controlled to limit spontaneous nucleation.

Liquid phase epitaxy of III-V materials and alloys

A method for the rapid and controlled synthesis of mixed metal oxide nanoparticles using relatively low temperature plasma oxidation of liquid droplets of predetermined mixed metal precursors is disclosed. The resulting nanoparticles reflect the metal precursor stoichiometries and the mixed metal oxide's metastable phase can be controlled. The synthesis of mixed transition metal oxide comprising binary metal oxides, ternary mixed metal oxides, quaternary mixed metal oxides and pentanary mixed metal oxides are demonstrated herein.
