Embodiment Construction

[0030] The present invention is directed to some semiconductor-based phase change media used in ultra-high density data storage devices. Recently, GeSbTe and its composites are widely used in optical recording devices, such as writable optical discs and DVD-RAM, by changing the data bit storage area of ​​GeSbTe media from amorphous to crystalline and from crystalline to amorphous A method to write data bits in this writable optical disc and DVD-RAM, and read data from GeSbTe media by detecting the difference in light reflectivity of amorphous GeSbTe and crystalline GeSbTe.

[0031] Some composites of GeSbTe have also been proposed for use as ultra-high density data storage devices. In such devices, the bit storage region acts as a miniature photoconductive, photovoltaic, cathodoconductive, cathodophotovoltaic, photoluminescent, or cathodoluminescent device that reacts when exposed to electromagnetic radiation or electrons. Significantly different electrical signals can be pro...

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.

Description

technical field [0001] The present invention relates to an ultra-high-density data storage medium for permanent electronic data storage devices, in particular to a semiconductor compound composed of a class of 13 / III group metals and 16 / VI group chalcogenides, this type of semiconductor The compound possesses some phase transition properties and electronic properties that allow multiple writing of bit storage areas within data storage media and use as micro-photoconductivity, photovoltaics, photoluminescence, cathode ray conductance, cathode ray photovoltaics Semiconductor devices such as lasers, or cathode ray luminescence, thereby facilitating data retrieval. Background of the invention [0002] Figure 1-Figure 3 The graph shows the energy level distribution of the quantum states of valence electrons in metals, insulators, and semiconductors at 0°K. At 0°K, the energy level of the highest energy state occupied by electrons is called the Fermi energy, E F . exist Figur...
