Fig. 2From: Effective passivation of Ag nanowire-based flexible transparent conducting electrode by TiO2 nanoshellCharacterization of the Ag-NW TCEs before TiO2 nanoshell coating. a SEM images (scale bar 20 μm), b X-ray diffraction pattern, c transmittance (inset: optical images), and d sheet resistance of Ag-NW TCEs as a function of the Ag-NW coating cycles. Laminated Ag-NW TCE (4 cycles) is shown in c and d for comparisonBack to article page
