The first demonstration of a rolled‐up InAs quantum dot tube photodetector is reported, which is fabricated by the selective release of self‐organised InAs/GaAs quantum dot heterostructures from the host substrate. The device exhibits a responsivity of ∼66 mA/W and an external quantum efficiency of ∼8% under 1064 nm excitation at 300 K.
