a I–V characteristic of WS2 nanotubes crossbar device in the linear coordinate for ten cycles. b I–V characteristic in the logarithmic coordinate for ten cycles. c The measured high resistance (HR, or OFF-state, by purple bars), low resistance (LR, or ON-state, by yellow bars), and the ON/OFF ratio (blue square) of the device, read at V = 1 V. d Switching voltage of the device for 10 cycles and the average value (dotted lines). The measurement is conducted at room temperature unless specified.
