Room temperature carbon annotates bolometer detector for infrared radiation

Abstract EN

Since the thermal detector play a very important role in the mid- Infrared and longer wavelength region.

The Bolometer which turn the change in resistance of active material to the voltage responsivity can be consider as a highly efficient detector.

The carbon nanotubes immersed in Polyvenalydene Fluoride (PVDF) polymer was fabricated between two metallic electrodes to form a thin film Bolometer.

This structure simplify the design of the bolometric detector and give rise to high efficiency through the extended heat sink electrode.

The temperature coefficient of the resistance was calculated and the responsivity of the detector was about 2V/W.

The time response of this detector was found to be about 200μs.
