摘要

We report on a room temperature Aerosol Jet printed two-terminal WSe2 crossbar architecture device on flexible substrate that achieves dual functionality of both a resistive random access memory (ReRAM), as well as a photosensor. As a ReRAM, the silver contacted WSe2 device exhibits forming free, sub 1-V switching voltage, and an on-off ratio of 2 orders. Furthermore, the WSe2 ReRAM exhibits both volatile and non-volatile switching behavior with a transition set current of 2 mu A, translating to a low operating power of 16 mu W. As a photosensor with the same architecture, the transparent CNT electrodes contacted device allows incident light to pass through for photocurrent generation. The two terminals device allows photo sensitivity to be tuned by bias application. In such mode, a maximum photo responsivity of 1 A/W at a visible light wavelength of 660 nm is exhibited by the device at a bias of 1 V, allowing weak light signals to be amplified. In both cases, the WSe2 device retains its functionality even after bending down to a radius of 5 cm. The fabrication process can be up-scaled and has great potential to be used for conformal electronics system integration.
