Abstract:The
bolometer is developed using single-walled carbon nanotubes
(SWCNT) anchored with semiconductor nanoparticles of cadmium sulfide,
stannous disulfide, and zinc oxide (ZnO). The bolometric responses
were recorded at varying temperatures from 10 K to room temperature.
The anchored SWCNTs provided a higher temperature coefficient of resistance
(TCR) than pristine SWCNTs. The largest TCR is recorded from SWCNTs/ZnO
(−0.11%/K) at room temperature, which is 200% higher than pristine
SWCNTs. The largest photorespo… Show more
