Investigation of Carbon Nanotubes as Low Temperature Sensors

Abstract

Low‐temperature resistance measurement of CVD‐grown carbon nanotubes has been carried out. Carbon nanotubes (CNTs) were grown on nickel film deposited on float glass substrate using an ion beam deposition technique. It was observed that nickel metal on the float glass behaves as metal. CNT's grown on this film behave as semiconductors. The resistance variation in the temperature range is drastic and indicates that it can be used as a low‐temperature sensor.
