Determination of unit-cell parameters from an electron diffraction pattern containing high-order Laue zone (HOLZ) reflections. (a) Schematic of reciprocal-lattice layers projected to form an electron diffraction pattern containing HOLZ reflections. (b) Calculation of the reciprocal-lattice layer spacing H* by measuring the radius of the HOLZ ring RH. (c) Geometrical construction of a 3D primitive cell in reciprocal space. (d) Graphical user interface of the package UnitCell Tools. |
