Abstract

SnO2-sensors were obtained by two different methods. The first one is based on platinum contacts
deposition to individual nanowire by FIB. Another one type of sensor was obtained by sol-gel process, based
on calcination of SnO2-nanopowder. Both types of sensors were able to detect 1 ppm of hydrogen sulfide and
acetone. Sensor responses were demonstrate high reproducibility. Sensor, based on SnO2 individual
nanowire, was more sensitive and stable than one, obtained by sol-gel method.
