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,...
It has been demonstrated that carbon nanotube field effect transistor (CNTFET) is a promising device to improve the performance of carbon nanotube (CNT) infrared (IR) sensors by modulating the doping level of the CNT channel. However, how to optimize the performance of the CNTFET based IR sensor is not well understood. In particularly, there was limited study on the design of transistor's gate structure,...
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...
