WebNov 1, 2011 · As shown in Fig. 1 (a), the XRD pattern of the Bi 2 Te 3 film deposited at 2.0 Pa exhibits only diffraction peaks from ( 00 l) planes, indicating highly preferential orientation of ( 00 l) planes. Seen from Fig. 2 (a), the surface topography of the film is composed of hexagonal crystals. WebJan 29, 2024 · The results show that the corrosion resistance of the (001) crystal plane is better than that of the (110) and (111) crystal orientations after long-term immersion, which is mainly attributed to the lower surface energy and higher R t of the (001) crystal orientation. Moreover, the uniform potential distribution on the (001) crystal plane also ...

WebAug 28, 2024 · Crystal Planes. Planes in a crystal can be specified using a notation called Miller indices. The Miller index is indicated by the notation [hkl] where h, k, and l are reciprocals of the plane with the x, y, and z axes. To obtain the Miller indices of a given plane requires the following steps: The plane in question is placed on a unit cell.
