Abstract:
Provided is a 2-terminal semiconductor device that uses an abrupt MIT semiconductor material layer. The 2-tenninal semiconductor device includes a first electrode layer, an abrupt MIT semiconductor organic or inorganic material layer having an energy gap less than 2eV and holes in a hole level disposed on the first electrode layer, and a second electrode layer disposed on the abrupt MIT semiconductor organic or inorganic material layer. An abrupt MIT is generated in the abrupt MIT semiconductor material layer by a field applied between the first electrode layer and the second electrode layer,
Abstract:
PURPOSE: A method for manufacturing an optical device with a thin film type nonlinear current characteristic is provided to obtain a nonlinear current characteristic using the optical device which reacts with the light from a light emitting diode. CONSTITUTION: A zinc oxide is deposited by a sputtering method using a zinc oxide target(S100). A deposition process is performed under an argon atmosphere without the oxygen injection. The nitrogen is additionally injected in a deposition thickness of 50 to 1000 nm. A thermal process is performed under the oxygen atmosphere after a thin film deposition process(S110). The thermal process is performed by an in-situ method using a growth chamber in a vacuum state or an ex-situ process using a thermal chamber outside the vacuum state. A deposition temperature is between a room temperature and 400 degrees centigrade. The temperature of the thermal process is between 100 to 600 degrees centigrade.
Abstract:
Provided is a metal-insulator-transition switching transistor with a gate electrode on a silicon substrate (back-gate structure) and a metal-insulator-transition channel layer of VO2 that changes from an insulator phase to a metal phase, or vice versa, depending on a variation of an electric field, and a method for manufacturing the same, whereby it is possible to fabricate a metal-insulator-transition switching transistor having high current gain characteristics and being stable thermally.
