Experiments in surface science often require samples made of high quality single crystals with surfaces containing little defects. However, at temperatures of around −10 ∘C, ice is a comparatively ductile material, making surface preparation challenging. We studied the near surface structure of ice single crystals prepared by different protocols using high resolution X-ray diffraction. Analysis of the diffraction data revealed that mechanical treatment can introduce distortions ranging up to several millimeters inside the bulk ice.
