    摘要: Provided is a method of fabricating a nano-wire array, including the steps of: depositing a nano-wire solution, which contains nano-wires, on a substrate; forming a first etch region in a stripe shape on the substrate and then patterning the nano-wires; forming drain and source electrode lines parallel to each other with the patterned nano-wires interposed therebetween; forming a plurality of drain electrodes which have one end connected to the drain electrode line and contact at least one of the nano-wires, and forming a plurality of source electrodes, which have one end connected to the source electrode line and contact the nano-wires that contact the drain electrodes; forming a second etch region between pairs of the drain and source electrodes so as to prevent electrical contacts between the pairs of the drain and source electrodes; forming an insulating layer on the substrate; and forming a gate electrode between the drain and source electrodes contacting the nano-wires on the insulating layer. Accordingly, even in an unparallel structure of nano-wires to electrode lines, a large scale nano-wire array is practicable and applicable to an integrated circuit or display unit with nano-wire alignment difficulty, as well as to device applications using flexible substrates.

    摘要: Provided are a structure and operating method of a semiconductor gas sensor having low power consumption. The semiconductor gas sensor is adapted to adsorb gas to a low-dimensional semiconductor nanomaterial at room temperature, output a change in resistance of the low-dimensional semiconductor nanomaterial, apply power to a heater, desorb the gas adsorbed to the low-dimensional semiconductor nanomaterial, and return the resistance of the low-dimensional semiconductor nanomaterial back to initial resistance. The semiconductor gas sensor senses the gas at room temperature using the low-dimensional semiconductor nanomaterial having a high-sensitivity characteristic at room temperature, and drives the heater only when the adsorbed gas is desorbed. Thereby, it is possible to improve a gas sensing characteristic, reduce power consumption, and provide a rapid response speed.
