(a) Deformation of the MoS2 monolayer under different forces applied by the AFM tip. Optical image of the measured MoS2 device (inset) denoting the tested 2.5 × 2.5-μm2 area by a black dashed rectangle. (b) I–Vb curves of the measured MoS2 device under a force applied in the centre of the tested region cycled from 0 to 12.5 nN and back to 0 nN, where the inset reveals the measured current under variable mechanical load at a fixed bias voltage of 0.55 V.
