The work at Purdue on germanium informed the work at Bell Laboratories that led to their pointcontact germanium transistor. [Petritz 1962, ...
A research collaboration consisting of IHPInnovations for High Performance Microelectronics in Germany and the Georgia Institute of Technology has demonstrated the world's fastest siliconbased device to date. The investigators operated a silicongermanium (SiGe) transistor at 798 gigahertz (GHz) fMAX, exceeding the previous speed record for silicongermanium chips by about

The result was the first transistor—the amplifier and switch that was, arguably, the greatest invention of the 20th century. Thanks to Moore's Law, the transistor has delivered computers far beyond anything thought possible in the 1950s. Despite germanium's starring role in the transistor's early history, it was soon supplanted by silicon.

Germanium reacts slightly with hydrogen at 1000°1100° C, giving germane, (GeH) x, which is an unstable and readily volatile compound. Germanium hydrides of the series Ce n H 2n + 2, up to Ce 9 H 20, may be produced by reacting germanides with dilute hydrochloric acid.
With a rack of PC boards, cleverly hinged to save space and stuffed with germanium transistors, a CRT display, and an acoustic delayline memory, the calculators look ridiculous by today's ...

This Fuzz Face Distortion is constructed to vintage specs, featuring the original Germanium PNP transistor design for a rich, creamy fuzz sound.
Uses Of Germanium. Germanium acts as a semiconductor, commonly doped with arsenic and other elements and used as a transistor in different electronic applications. The oxides of Germanium includes a high index of dispersion and refraction which makes it perfect to use in wideangle camera lenses objective lenses for microscopes.
This element is a grayishwhite, lustrous, brittle metalloid. Although germanium is a poor conductor of electricity, it is often doped with other elements and is used as a transistor element in thousands of electronic applications. Germanium is most important as a semiconductor material and it is in this area that the majority of germanium is used.
In such cases, denoted as Ge/Si, in which the concentration of germanium in the core is higher than the concentration of silicon in the (incomplete) shell, the reverse ratio of atoms was used: 29/6, 29/18, 53/18, 71/28, and 87/60.
A transistor is a semiconductor device commonly used as an amplifier or an electrically controlled switch. The transistor is used in a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators .

A transistor, also known as a BJT (Bipolar Junction Transistor), is a current driven semiconductor device which can be used to control the flow of electric current in which a small amount of current in the Base lead controls a larger current between the Collector and Emitter.

Germanium really took off with the development of the transistor, a solid state version of the triode valve. Here a small current can be used to control a larger one, amplifying a signal or acting as a switch. Germanium transistors were very common, but now have been replaced by silicon.
