1. Method for crystal growth from a surfactant of a metal nonmetal (MN) compound, comprising the procedures of:

  • providing a seed crystal;

    introducing atoms of a first metal to said seed crystal in order to form a thin liquid metal wetting layer on at least one surface of said seed crystal;

    setting a temperature of said seed crystal below a minimal temperature required for dissolving MN molecules in said thin liquid metal wetting layer and above a melting point of said first metal, each one of said MN molecules being formed from at least one atom of a second metal and at least one atom of a first nonmetal;

    introducing said MN molecules which form an MN surfactant monolayer, thereby facilitating a formation of said thin liquid metal wetting layer between said MN surfactant monolayer and said at least one surface of said seed crystal; and

    regulating a thickness of said thin liquid metal wetting layer such that at least some of said MN molecules of said MN surfactant monolayer couple with said at least one surface of said seed crystal, thereby growing an epitaxial layer of said MN compound on said seed crystal.
