Nonlocal Response in Infrared Detector with Semiconducting Carbon Nanotubes and Graphdiyne

Semiconducting single‐walled carbon nanotubes (s‐SWNTs) are regarded as an important candidate for infrared (IR) optical detection due to their excellent intrinsic properties. However, the strong binding energy of excitons in s‐SWNTs seriously impedes the development of s‐SWNTs IR photodetector. Thi...

description Semiconducting single‐walled carbon nanotubes (s‐SWNTs) are regarded as an important candidate for infrared (IR) optical detection due to their excellent intrinsic properties. However, the strong binding energy of excitons in s‐SWNTs seriously impedes the development of s‐SWNTs IR photodetector. This Communication reports an IR photodetector with highly pure s‐SWNTs and γ‐graphdiyne. The heterojunctions between the two materials can efficiently separate the photogenerated excitons. In comparison to device fabricated only with s‐SWNTs, this IR detector shows a uniform response in the whole channel of the device. The response time is demonstrated to be below 1 ms. The optimal responsivity and detectivity approximately reach 0.4 mA W(−1) and 5 × 10(6) cmHz(1/2) W(−1), respectively.
