Active area dependent photocurrent measurements. (a–g) False coloured FESEM images of different active areas and insets (I- VI) show the zoom section of constricted WTe2 channel respectively. Curves (orange and magenta) on top of FESEM images represent time dependent photocurrent measurements performed at bias voltages 0.5 V and 2 V respectively. (h,i) Show the responsivity (blue) and detectivity (red) curves at bias volt 0.5 V and 2 V respectively.
