Appearance of ductility in germanium single crystals as a result of slow loading


The effect of slow loading (350 g/mm2 per h) on the deformation resistance of n- and p-type germanium single crystals is studied. In the presence of a smoothly-increasing load, germanium single crystals undergo up to 22% deformation at 400°C without rupture. Germanium crystals subjected to preliminary slow loading yield in a plastic manner on subsequent subjection to ordinary tensile tests, even in the temperature range corresponding to the brittle fracture of the original samples.
