Germanium is a chemical element with symbol Ge and atomic number 32. It is a lustrous, hard, grayishwhite metalloid in the carbon group, chemically similar to its group neighbours silicon and germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.

Silicon Germaniumoninsulator (SGOI) is a technology analogous to the SiliconOnInsulator (SOI) technology currently employed in computer chips. SGOI increases the speed of the transistors inside microchips by straining the crystal lattice under the MOS transistor gate, resulting in improved electron mobility and higher drive currents.
