摘要： 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.

摘要： 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.

The reformer includes a reforming unit configured to have a reforming reaction generated therein, a combustion unit configured to supply heat energy to the reforming unit, and a carbon monoxide reduction unit configured to reduce the concentration of carbon monoxide in a reformed gas discharged from the reforming unit. A combustion gas pipe is connected to the combustion unit. A reformed gas pipe is disposed between the reforming unit and the carbon monoxide reduction unit. At least one of the combustion gas pipe and the reformed gas pipe is configured to pass through the inside of the water tank or to raise a temperature of the water tank through contact with the water tank, thereby preventing the freezing of the water tank.
