摘要

The individual single crystalline and polycrystalline single SnO_2 nanowire sensors have been fabricated on the base of the NIST micro-hot plates. Using Scanning Photoelectron Microscope (SPEM) with the lateral resolution of ca 80 nm we were able to access spectroscopicaly (XPS) the changes of surface chemistry of the individual nanowires during their operation. It was possible in real time to monitor the changes in conductance of the nanowire upon redox gas exposure and link them to the formation of the specific surface groups. The effect of crystallinity of the nanowires and electroactive defects on their sensing performance has been studied.
