The Tanaka Kikinzoku Group, founded in 1885, is a Japanese manufacturer of precious metals materials focusing mainly on products for the electronics, semiconductor and automotive industries. [2] Tanaka's European subsidiary is Tanaka Kikinzoku International (Europe) GmbH in Frankfurt , Germany and its US subsidiary is Tanaka Kikinzoku ...
In 1919, KEMET Laboratories was founded by Union Carbide Corporation to capitalize on its purchase of Cooper Research Company of Cleveland, Ohio. Cooper had developed an alloy that could be used in the manufacture of vacuum tube components.
Heraeus is a German technology group with a focus on precious and special metals, medical technology, quartz glass and sensors as well as electronic components. Founded in Hanau in 1851, the company is one of the largest family-owned companies in Germany in terms of revenue.
Solar cells could be fabricated directly on the lunar soil by a medium-size (~200 kg) rover with the capabilities for heating the regolith, evaporation of the appropriate semiconductor materials for the solar cell structure directly on the regolith substrate, and deposition of metallic contacts and interconnects to finish off a complete solar ...
Germanium is a semiconductor having an indirect bandgap, as is crystalline silicon. Zone refining techniques have led to the production of crystalline germanium for semiconductors that has an impurity of only one part in 10 10 , [ 37 ] making it one of the purest materials ever obtained. [ 38 ]
Umicore's third business segment, its largest in terms of revenue, [4] is composed of two subdivisions, Automotive Catalysts and Precious Metals Chemistry. In automotive catalysts, a field in which the company had begun research in 1968, [33] the company ranks third in global market share [34] behind BASF Catalysts (formerly Engelhard) and ...
The boules may be either semiconductor (e.g. electronic chip wafers, photovoltaic cells) or non-conducting inorganic compounds for industrial and jewelry use (e.g., synthetic ruby, sapphire). Single crystal ingots of metal are produced in similar fashion to that used to produce high purity semiconductor ingots, [ 3 ] i.e. by vacuum induction ...
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
