Surface morphologies of the bare glass and silicon substrates and the substrates coated with gold were examined by AFM method, and the typical AFM images are shown in Figures 2 and 5. Bare Si surface exhibits flat morphology with low surface roughness not exceeding 0.2 nm.
The surface morphology of a bare non-selenized CIGS solar cell is shown in Figure 1a.
The surface morphology of the bare GCE and modified electrodes were characterized by SEM and TEM.
To further analyse the effect of sensitization time on the SnO2 photoelectrode, morphology of both bare and sensitized photoelectrode was studied.
Effect of morphology of the bare hybrid structure was systematically investigated by varying the weight ratios of GNPs and MWCNTs.
The surface morphology and structure of bare and coated LiCoO2 is characterized by scanning electron microscope (SEM) and X-ray diffraction spectroscopy (XRD).

For example, Liu et al. studied the morphology-dependent photocatalytic properties of bare zinc oxide nanocrystals [11], which indicated that the rod-shaped ZnO nanostructures have higher photocatalytic activity than the multi-layer disks or truncated hexagonal cones.
