One of which was the high speed which electrons move through silicon, also referred to as “carrier mobility.”Silicon-germanium - Wikipedia,Silicon Germanium-on-insulator (SGOI) is a technology analogous to the Silicon-On-Insulator (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.

Germanium - Wikipedia

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon.Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.300-1969 - reference.globalspec,Both silicon and germanium detectors have been developed, with silicon finding its principal application in the detection and analysis of heavy charged particles.
