– The results of research aimed at the gas sensing nanowires (NWs) engineering are presented. Structurally modulated SnO2 NWs were obtained at 900°C in the modified vapor-solid process, allowing that NW morphology could be encoded in a programmable way along its length. PVD technique was used for Ti/Au electrical contacts deposition and gas sensitive nanoscale chemiresistors formation.
Created nanostructures were characterized for their gas sensing performance. It was established that structurally-modulated NWs possess better gas sensitive characteristics in comparison with the straight ones. Obtained results are discussed from the positions of single-crystal “necks” formation in NWs.
