This paper reports the integration of the helical nanobelts (HNBs) onto carbon nanotube (CNT)-based infrared (IR) sensors to enhance their sensitivity by improving the fill factor. The repeatable and controllable assembly process is achieved by employing nanorobotic manipulation. The enhancement after integration is confirmed by the electromagnetic simulation. Based on the simulation result, the integration...
Carbon nanotube (CNT), a one dimensional (1D) hollow cylinder, possesses exceptional optoelectronic properties due to its unique geometry, making it a promising material for infrared (IR) detection. By taking advantage of its particular features, IR detectors using CNT have the potential to outperform and replace conventional detectors. In this paper, a multi-spectrum IR detector system will be introduced,...
Carbon nanotube (CNT) is a novel one dimensional (1D) material that has unique electrical and optoelectronic properties. Photo-sensors using CNT can sense infrared signals by using Schottky barriers between metal and nanotube, which are able to separate photo-generated electron-hole pairs in order to generate photocurrent or photovoltage for detection and quantification. It has been demonstrated that...
Single wall carbon nanotube (SWCNT) is a promising one dimensional (1D) material to fabricate high performance infrared (IR) detectors owing to its unique electrical and physical properties. The 1D Schottky barrier between metal and CNT can separate the photon-generated electron-hole pairs so as to produce photocurrent for quantification and detection. However, the theory developed for the planar...
