格子定数（こうしていすう、こうしじょうすう、lattice constant）とは、結晶軸の長さや軸間角度のこと。単位格子の各稜間の角度 α,β,γ と、各軸の長さ a,b,c を表す6個の定数である 。その性質上、格子の形状によっては一部の値のみで表すことが出来る。例えば、立方格子ではa = b = cかつα = β = γ=90°であるため、aの値のみで表すことができ、斜方格子ではα = β = γ=90°であるため、a,b,cのみを指定すればよい 。 Web26 mrt. 2024 · The orientation-dependence of thin-crystal lattice fringes can be gracefully quantified using fringe-visibility maps, a direct-space analog of Kikuchi maps. As in navigation of reciprocal space with the aid of Kikuchi lines, fringe-visibility maps facilitate acquisition of 3D crystallographic information in lattice images. In particular, these maps …
WebAlthough more than one contrast mechanism can create them, lattice fringes are often made visible by electron-phase-contrast in a conventional high resolution electron microscope (HRTEM). This type of contrast maps high-energy electron deBroglie phase shifts at the exit surface of the specimen by recording intensity variations that result from ...

Web16 sep. 2024 · Asshowninfigure1(a) the super-lattice contains two regions, namely a 2D lattice extending to the end of fiber-1 and a 1D wave-like pattern starting from the fiber-1 end. The 1D fringes bend towards step-2 and terminate at this step. The 2D lattice continues beyond the fiber-2 end but terminates at step-2 in this image. WebLattice fringes belonging to different beam pairs, +g and -g, are shifted differently resulting in an asymmetry of the HRTEM image. [Pg.380] One typical delocalization effect is that …
