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 ...
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).
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 ...
Platinum–iridium alloys are alloys of the platinum group precious metals platinum and iridium. Typical alloy proportions are 90:10 or 70:30 (Pt:Ir). These have the chemical stability of platinum, but increased hardness. The Vickers hardness of pure platinum is 56 HV while platinum with 50% of iridium can reach over 500 HV.
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 ...
Palladium has the appearance of a soft silver-white metal that resembles platinum. It is the least dense and has the lowest melting point of the platinum group metals. It is soft and ductile when annealed and is greatly increased in strength and hardness when cold-worked.
