Paper Abstract

A new nanopolycrystal of vanadium dioxide has been prepared. The average grain size is 8-10nm and the phase transition temperature drops down to 35°C. The temperature coefficiency of resistance (TCR) is 6-7%/°C in semiconductor zone. A linear senor has been fabricated based on the nanostructure of vanadium dioxide thin films and the test indicates that the characteristics has been improved greatly compared with sensors based on using conventional vanadium dioxide thin films.
