【Abstract】 The semiconducting mechanism, applications and fabrication techniques ofITO films are reviewed. The semiconducting mechanism of ITO is attributed to doping with Sn4+ and to oxygan vacancies. The semiconducting transparent ITO films are mainly used in optical-electrical devices such as LCD (liquid crystal display) device. Various fabrication techniques cur-rently in use, including magnetron sputtering, CVD, sol-gel, spray-pyrolysis, are discussed.更多还原
