Crystal structure of germanium
WebGermanium (Ge) is the second most popular indirect bandgap (0.66 eV at bulk scale) semiconductor in group IV widely used in microelectronic applications. Generally, Ge nanoparticles are grayish black powder with an average size of 70–120 nm. Usually, Ge is found in diamond crystal structure, which may vary in a cluster of more than 40 atoms. WebThe germanium atoms will share valence electrons in a covalent bond. This is shown in the following figure. Germanium are the ones that are associated with the covalent bonding.

WebJan 20, 2024 · Crystal structures. Most metals and alloys crystallize in one of three very common structures: body-centered cubic (bcc), hexagonal close packed (hcp), or cubic close packed (ccp, also called face centered cubic, fcc). In all three structures the coordination number of the metal atoms (i.e., the number of equidistant nearest … WebThe crystal structure of all these semiconductors is shown as diamond. The difference between them is in the conducting properties between metals and insulators. Diamond behaves much more like an insulator; meanwhile tin is much like a metal. Between them silicon and germanium perform as two typical semiconductors.
