| 20110227061 | SEMICONDUCTOR OXIDE NANOFIBER-NANOROD HYBRID STRUCTURE AND ENVIRONMENTAL GAS SENSOR USING THE SAME - Provided is an environmental gas sensor including an insulating substrate, a metal electrode formed above the insulating substrate, and a sensing layer formed of a semiconductor oxide nanofiber-nanorod hybrid structure above the metal electrode. The environmental gas sensor can have excellent characteristics of ultra high sensitivity, high selectivity, high responsiveness and low power consumption by forming a semiconductor oxide nanorod having high sensitivity to a specific gas on a semiconductor oxide nanofiber. | 09-22-2011 |
