    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 tera-hertz continuous wave generator is provided to establish a wired/wireless ultra-wideband convergence network with super high speed without discontinuity and delay through seamless connection with an optical network. CONSTITUTION: An optical intensity modulator(20) modulates an inputted optical signal into a double sideband optical signal by using frequencies and power from a local oscillator(30). The local oscillator generates a modulated signal for modulating the optical signal inputted in the optical intensity modulator into the double sideband optical signal. An optical fiber amplifier(40) amplifies an output signal from the optical intensity modulator. An optical circulator(50) transfers the optical signal inputted in the optical fiber amplifier to a notch filter(60). The notch filter filters the optical signal inputted from the optical circulator. An opto-electric converter(70) is used as a photo mixer photo-mixing the double sideband signal outputted from the notch filter.

    Abstract: Provided are a field emission device and a field emission display device using the same. The field emission device includes a cathode portion having a substrate, a cathode electrode formed on the substrate, and a field emitter connected to the cathode electrode; a field emission-suppressing gate portion formed on the cathode portion around the field emitter and surrounding the field emitter; and a field emission-inducing gate portion having a metal mesh with at least one penetrating hole, and a dielectric layer formed on at least a part of the metal mesh, wherein the field emission-suppressing gate portion suppresses electrons from being emitted from the field emitter, and the field emission-inducing gate portion induces electrons to be emitted from the field emitter. According to this configuration, the conventional problems of the field emission device including a gate leakage current, electron emission caused by an anode voltage, electron beam divergence can be significantly improved.
