Silicon-germanium
Silicon-germanium. SiGe ( ˈsɪɡɪː ), or silicon-germanium, is a general term for the alloy Si 1-x Ge x which consists of any molar ratio of silicon and germanium. It is commonly used as a semiconductor material in integrated circuits (ICs) for heterojunction bipolar transistors or as a strain -inducing layer for CMOS transistors.

How Semiconductors Work | HowStuffWorks
Silicon sits next to aluminum and below carbon in the periodic table. . Carbon, silicon and germanium (germanium, like silicon, is also a semiconductor) have a unique property in their electron structure -- each has four electrons in its outer orbital. This allows them to form nice crystals. The four electrons form perfect covalent bonds …

Germanium-based Transistors for Future High Performance and …
High mobility channel materials could replace strained Si to enhance speed performance and/or reduce power consumption in future transistors. Ge has the highest hole mobility among common elemental and compound semiconductors, and an electron mobility that is two times larger than that of Si. Ge is thus a promising channel material for future CMOS …

Germanium and SiGe may get another chance
Furthermore, silicon became the semiconductor material of choice due to superior temperature-related attributes, lower cost, and wider availability of raw material. Germanium does have a lower forward-voltage drop of about 0.4 V versus 0.7 V for silicon. However, the higher silicon drop is outweighed by its many other virtues.

What Is Silicon Germanium's Place at the Semiconductor Table?
Later, Meyerson discovered that when silicon was cleansed in hydrofluoric acid, a protective hydrogen layer would form, negating the need to heat silicon to 1000°C to rid silicon of the contaminating oxide. At 600°C, the hydrogen layer blows off and creates oxide. This discovery allowed scientists at IBM to grow silicon germanium at 550°C.

Semiconductor (Material)
For gamma rays, it is more attractive to use germanium rather than silicon because of its higher atomic number (32 versus 14). Even with the larger photoelectric cross section of germanium, it is unlikely that a gamma ray of typical energy will be fully absorbed in an initial photoelectric interaction. Instead, Compton scattering is generally ...
