Notes:
The influence of thermal atomic vibrations in high-resolution electron microscopy is modeled by combining time-resolved molecular dynamics simulations with the multislice algorithm of HREM image simulation. The material studied is stoichiometric NiAl-B2 at room temperature and at 900 K. The difference between the new method of image calculation and conventional calculations by Debye–Waller factors and absorption parameters is examined in detail. The difference between images calculated with and without thermal diffuse scattering (TDS) is found to be surprisingly small owing to the small thickness of typical HREM specimens of about 10 nm.
