Accuracy of Strain Measurement by CBED

A highly accurate measurement with CBED technique can be achieved through the analysis of higher-order Laue zone (HOLZ) patterns using the least-square fitting of distances of HOLZ line intersections between the observations and calculations.

Note that the accuracy of strain measurements by using CBED technique is affected by broadening and/or splitting of the HOLZ lines that is induced by curvature of atomic lattice.
