• Coordinates in square brackets such as [100] denote a direction vector (in real space). • Coordinates in angle brackets or chevrons such as <100> denote a family of directions which are related by symmetry operations. In the cubic crystal system for example, <100> would mean [100], [010], [001] or the negative of any of those directions. WebInterestingly, In-doping subtly changes the relationship of surface energy of (1 1 0), (2 1 1), and (2 0 0) planes, and the order of surface energy is Ē(2 1 1)> Ē(1 1 0)> Ē(2 0 0). This result indicates that In-doping makes the (2 0 0) plane of Li-In have the lowest surface energy. Therefore, it can induce the as-deposited Li to realize the ...
