a Schematic diagram of a single CNF/TiO2 core–shell NW device. b SEM image of a device used in the study. Inset shows a four-probe device used to measure contact resistance and resistivity. c TEM image showing the core–shell structure of the CNF/TiO2 NW. The yellow dashed line shows the interface between the TiO2 shell and CNF core. d Microstructure of the core–shell NW, insets give the FFT results for the shell and core, respectively
