Highly purified carbon nanotube cascading IR detectors are constructed, in which virtual contacts are used to multiply photovoltage and improve the signal‐to‐noise ratio. It exhibits a broadband response, high room temperature detectivity of 2.91 × 10 11 Jones, extremely good temperature and temporal stability and large scale fabrication potential of 150 × 150 photodetector array with random test yield of 100%.
