xHREMTM: HREM Simulation Suite

New Version (v4.5) is available now!
xHREMTM (WinHREMTM/MacHREMTM) is a suite of the high-resolution electron microscope (HREM) simulation programs that will run under both Windows and Max OS. This emerges from the HREM image simulation programs based on FFT multislice technique developed at Arizona State University, USA. This is one of the most reliable and efficient HREM image simulation programs in the world. Computing speed is optimized by using Intel's Math Kernal Library (MKL).

xHREMTM has been developed for the image simulation for Transmission Electron Microscope (TEM) and enforced by two options used to simulate Convergent Beam Electron Diffraction (CBED) and Scanning Transmission Electron Microscope (STEM), respectively. Please consult each catalog listed below for more information.

xHREM supports a multi-CPU machine and provides 64-bit versions. Furthermore, 32- and 64-bit cluster versions for STEM Extenstion are avairable.

Furthermore, a computation time of STEM image simulation can be reduced to 1/20 compared with the versions before v3.6 using an efficient interpolation method. Thus, one day calculation in the past can be done just within one hour. We recommend to use this version especially for a STEM simulation.

This version has a user interface to handle a non-periodic (non-crystal) model.
