Figure 5
The HREM image of a TiO2 nanocrystal and selection of experimental templates. (a) shows the overall shape of the nanocrystal, which was imaged with a dose of 105 (e Å−2) s−1 and 10 s exposure time under the environmental conditions of 2 × 10−5 Pa and 550°C. (b) shows a magnified view of the boxed region in (a). (c) displays the templates extracted from (b). Images in the left column are cropped directly from (b). Images in the middle column are spatially averaged over the masked area of (c). (c) is the masked image of Fig. 5(b). The coloured region indicates the area where the XC coefficient is above the threshold. |
