Germanium based metal-insulator transition thin film, metal-insulator transition device including the metal-insulator transition thin film, and method of fabricating the metal-insulator transition device
Germanium based metal-insulator transition thin film, metal-insulator transition device including the metal-insulator transition thin film, and method of fabricating the metal-insulator transition device
Provided are a germanium (Ge) based metal-insulator transition (MIT) thin film which is formed of a Ge single-element material instead of a compound material of two or more elements and by which material growth may be easily performed and a problem of a second phase characteristic in accordance with a structural defect and an included impurity may be solved, an MIT device including the MIT thin film, and a method of fabricating the MIT device. The MIT device includes a substrate; a germanium (Ge) based MIT thin film which is formed of a Ge single-element material on the substrate and in which a discontinuous MIT occurs at a predetermined transition voltage; and at least two thin film electrodes contacting the Ge based MIT thin film, wherein the discontinuous MIT occurs in the Ge based MIT thin film due to a voltage or a current which is applied through the thin film electrodes.
