WebJan 1, 2011 · 2.1. Band structures. In this chapter, electronic band structures of SiGe systems are described mainly from a theoretical point of view. The electronic band structures of bulk Si, bulk Ge, and SiGe alloys are first reviewed (Yu and Cardona, 1999, Hamaguchi, 2010).Then, strain effects on the electronic band structures of … 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…
