Crystal structure of germanium
Under standard conditions, germanium is a brittle, silvery-white, semi-metallic element. This form constitutes an allotrope known as α-germanium, which has a metallic luster and a diamond cubic crystal structure, the same as diamond. While in crystal form, germanium has a displacement threshold energy of . At pressures above 120 kbar, germanium becomes the allotrope β-germanium with the same structure as β-tin. Like silicon, gallium, bismuth, antimony, and water, g… WebS.N. Ruddlesden and P. Popper, “On the Crystal Structures of the Nitrides of Silicon and Germanium,”Acta Crystallogr, 11, 465 (1958).
