Improved multislice calculations for including higher-order Laue zones effects

► We have developed and tested a new method for including HOLZ effects in an efficient way in electron scattering simulations. ► The ICMS method has higher accuracy than the CMS method for the calculation of the ZOLZ, HOLZ and Pseudo-HOLZ reflections. ► ICMS method allows to use a larger slice thickness than the CMS method and reduces the calculation time.
