摘要: A high-sensitivity detector for opto-electronic detection using multiwall carbon nanotubes (MWCNTs) is provided. More specifically, multiwall carbon nanotube films demonstrate an infrared bolometric photoresponse higher than SWCNT films at room temperature. The observed D* exceeding 3.3×106 cm Hz1/2/W with MWCNT-film bolometers and can be further improved to over 1×107 cm Hz1/2/W by adding graphene flakes. The response time of about 1-2 milliseconds with MWCNT bolometers is more than an order of magnitude shorter than that of SWCNT bolometers. For individual MWCNTs with specially designed asymmetric Schottky contacts, one on the sidewall and the other covering the end, the photocurrent has been efficiently harvested and provides a higher detectivity of 6.2×109 cm·Hz1/2/W at room temperature, which is one order of magnitude higher than the convectional VOx detector and makes MWCNT competitive for practical optoelectronic detections over infrared and even longer wavelength range.
