Provided is a field effect transistor including an insulator-semiconductor transition material layer. The insulator-semiconductor transition material layer selectively provides a first state where charged holes are not introduced to a surface of the insulator-semiconductor transition material layer when a gate field is not applied and a second state where a large number of charged holes are introduced to the surface of the insulator-semiconductor transition material layer to form a conductive channel when a negative field is applied. A gate insulating layer is formed on the insulator-semiconductor transition material layer. A gate electrode is formed on the gate insulating layer to apply a negative field of a predetermined intensity to the insulator-semiconductor transition material layer. A source electrode and a drain electrode are disposed to face each other at both sides of the insulator-semiconductor transition material layer so that charge carriers can flow through the conductive channel while the insulator-semiconductor transition material layer is in the second state.

A current-jump-control circuit including an abrupt metal-insulator phase transition device is proposed, and includes a source, the abrupt metal-insulator phase transition device and a resistive element. The abrupt metal-insulator phase transition device includes first and second electrodes connected to the source, and shows an abrupt metal-insulator phase transition characteristic of a current jump when an electric field is applied between the first electrode and the second electrode. The resistive element is connected between the source and the abrupt metal-insulator phase transition device to control a jump current flowing through the abrupt metal-insulator phase transition device. According to the above current control circuit, the abrupt metal-insulator phase transition device can be prevented from being failed due to a large amount of current and thus the current-jump-control circuit can be applied in various application fields.

Provided is a 2-terminal semiconductor device that uses an abrupt MIT semiconductor material layer. The 2-terminal 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.
