Growth of Oriented SnO2 Thin Films from Organotin Compounds On Glass Substrates by Spray Pyrolysis

Tin(IV) oxide (SnO2) is an oxygen-defect type semiconductor with a wide band gap and a large mobility. It is transparent in the visible region, and reflective in the infrared region.1 Thus, SnO2 thin films have been used as transparent electrodes in sophisticated electrochromic, electroluminescent, and photoconductive devices.2 Recently, it has been also reported that gas sensitivity is high for (110) oriented SnO2 thin flms3 and a large electrical conductivity is obtained in (200) oriented SnO2 thin films.4
