Abstract

This study aims to investigate the noise properties of carbon nanotube (CNT) and thermally reduced graphene oxide (TRGO). The optical noise equivalent power (NEP) and optical detectivity were calculated using the responsivity, noise voltage, and area of the cell of the absorber. For CNT, the NEP and detectivity are 4.81×10-11 W/√Hz and 4.61×108 cm*√Hz/W, respectively. On the other hand, TRGO has an NEP of 3.19×10-9 W/√Hz and detectivity of 1.57×108 cm*√Hz/W. It was concluded that CNT has a better performance compared to TRGO because it has a higher responsivity, 440 V/W, and smaller cell area, 4.9x10-4 cm2.
