Abstract

Abstract : Multi-walled CNT p–n junctions are used to construct flexible infrared detectors. The structure of the detector is demonstrated to have excellent mechanical stability. Abstract : Different types of multi-walled carbon nanotubes (CNTs), synthesized by chemical vapor deposition, are used to fabricate infrared (IR) detectors on flexible substrates based on CNT p–n junctions. It is found that this kind of detector is sensitive to infrared signals with a power density as low as 90 μW mm −2 even at room temperature. Besides, unlike other devices, the detector with this unique structure can be bent for 100 cycles without any damage and its functionality does not degenerate once it recovers to the initial state. The results give a good reference for developing efficient, low-cost, and flexible IR detectors.
