Abstract:
We investigate the temperature coefficient of resistance and noise properties of polymer-infiltrated carbon nanotube membranes and their applications to infrared detection. In agreement with previous work the noise is found to be dominated by a 1/f contribution. We found, however, that small bolometric time constants, of ~ 10ms, are achievable in this system in reasonably large “pixels” of 50 um X 50 um, which is beneficial to future applications. Contrary to our expectations, the polymer-nanotube system did not exhibit a large temperature coefficient of resistance. The possible reasons are discussed.
