Assembling nanowires into highly ordered arrays is crucial for developing integration circuits. Oriented growth of mid-infrared Pb1- x Snx Te nanowire arrays on bendable mica, extending the function of existing nanowire arrays, is reported. The flexible photodetectors of these nanowire arrays show a high photoresponsivity of 276 A W(-1) (at 800 nm), which is higher than many previously reported infrared nanosensors.
