Figure 6. Electrical characteristics and flexibility of fiber-type transistor devices.

(a) Schematic illustration and optical image of a fiber-type transistor based on graphene/Ag hybrid fiber electrodes. (b) I_D–V_D and (c) I_D–V_G characteristics of the fiber-type transistors based on hybrid fiber electrodes with R_draw = 0.6. (d) Photograph of a fiber-shaped transistor wrapped around a glass rod (r = 2 mm). The inset shows the bent hybrid fiber electrodes along the curvature of the glass rod. (e) Changes in the transfer curves of the fiber transistor devices based on hybrid fibers (R_draw = 0.6) at different bending radii. (f) Changes in the hole mobilities of the fiber transistor devices based on hybrid fibers (R_draw = 0.6 and 1.2) and on the rGO fiber electrodes at different bending radii.
