Here, we demonstrate that single InAs nanowire (NW)-based field-effect transistor exhibits wavelength-selective switching between positive and negative photoresponses caused by abundant defect states on the NW surface. On this basis, by modifying the NW carrier transport behavior through the strong local electric field formed by polarized ferroelectric polymer P(VDF-TrFE), a rewritable NW memory device can be achieved with electrical bistability and low-power consumption when writing with...[Show more]
