3D assembly and simulation of helical optical antenna-enhanced carbon nanotube IR sensors

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 of HNB antenna can increase the local electric field by 58 folds, which makes the CNT-based IR sensors an ideal candidate for non-cryogenic highly sensitive IR detection.
