Indium surfide and gallium surfide for ultrahigh density data storage device and phase transformation meidum of indium-gallium surfide

Abstract

An ultra-high-density data storage medium (902) using indium chalcogenide, gallium chalcogenide, and indium-gallium chalcogenide thin films, the purpose of which is to form some photoconductive, photovoltaic, Or a bit storage area (904) that acts as a photoluminescent semiconductor device. These bit storage areas generate electrical signals when exposed to electromagnetic radiation; or form some areas that act as cathode ray conductors, cathode ray voltaics, or cathode rays. The light-emitting semiconductor device acts as a bit storage area (904) that generates an electrical signal when exposed to an electron beam. The two values ​​of the bit are represented by the two solid phases of the data storage medium, namely the crystalline phase and the amorphous phase. The transition between the two phases can be achieved by heating the bit storage area.
