摘要
Image contrast in transmission electron microscopy is often three or more times less than theory predicts. Recent off-axis holography suggests that the origin of this Stobbs factor may lie in thermal diffuse scattering. In the light of this result, possibilities for further observations by TEM, STEM, CBED and holography are suggested as well as frozen phonon computations that include flexural modes.
