N2 - Piezo-phototronic-effect possesses potential revolutionary applications in optoelectronic systems, malleable optical processing, biomedical diagnostics, and communication. Here, we report a novel structural device, dual piezo photo-transistor (DPPT), based on piezo invert-structured organic light emitting diode (OLED) as gate control and piezo nanowires (NWs) array as charge transport channel to realize tunable photoelectric properties dramatic enhancement achieved by piezo-phototronic-effect in both stimulation gate electrode and the metal-semiconductor-metal channel. Systematic analyses are carried out on electron generated as well as the electric field distribution under various bending/strain direction and degree with the c-direction ZnO NWs grown both vertically and horizontally in OLED gate and NW channel, respectively. The piezo-phototronic transistors under mechanical deformation yield a current on/off ratio of 106, more than 80 times higher as compared to the one without deformation. The enhancement of the integrated DPPTs, taking advantage of piezo-phototronic effect, may open up opportunities in innovative applications in various optoelectronic devices and flexible integrated systems.
