• germanium | Properties, Uses, & Facts | Britannica.com

    Germanium: Germanium, a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals. It did not become economically significant until after 1945, when its properties as a semiconductor in electronics were recognized.

  • Silicon & Germanium Crystal Structure - PhysicsOpenLab

    Diamond Cubic Crystal Structure. Silicon and Germanium are examples of covalent crystals. In these solids the atoms are linked to each other by covalent bonds rather than by electrostatic forces or by delocalized valence electrons that work in metals almost like a “glue”. The most classic example of covalent crystal is the diamond that belongs to the fcc cubic crystal system.
