Figure 1
(a) Photograph of the CeB6(001) single crystal. (b) Drawing of a pristine CeB6 surface in which areas for LEEM/PEEM/TEEM observations are indicated by red dots. (c) LEEM, (d) UV-PEEM and (e) TEEM images of pristine CeB6 at representative areas with different temperature. The diameter of the field of view is 75 µm for all the images. The grayscales of the images (shown by scale bars) are varied for different conditions in order to show the image contrast clearly. (f) Temperature dependence of the average TEEM image intensities. Note that the intensities at 1500°C were much higher than the detection limit and were not measured (dashed arrows are shown to indicate histories of annealing). |
