Facile fabrication of conducting polymer nanowire based field effect transistor with controlled shape and position

► Single conducting polymer nanowire is fabricated directly on the device platform. ► Facile method provids the controlled position, width, and length of nanowire. ► Nanowire is electrochemically deposited on the nanopatterned area of electrode. ► Polypyrrole nanowire based field effect transistor is successfully established.
