Highly sensitive, Si-integrated gas sensors based on undoped, In-and Sb-doped nanocrystalline SnO 2 -films, have been fabricated by spray pyrolysis. We have found that the In-doped gas sensors show significantly improved sensitivity for CH 4 detection and low sensitivity for H 2 detection, while Sb-
