Gallium arsenide phosphide is a semiconductor material and an alloy of gallium phosphide and gallium arsenide. It exists in various composition ratios denoted by x in its formula.
It has long been thought that ‘wonder material’ graphene will eventually herald a manufacturing revolution in the electronics and photonics industries. Yet these hopes are currently still purely theoretical. Now a surprising twist may show why this revolution has yet to come to fruition.

Indium gallium aluminum nitride is generally prepared by epitaxial methods like pulsed-laser deposition, molecular beam epitaxy, etc. Addition of indium to the gallium nitride to form the light-emitting layer leads to the emission of ultraviolet and visible lights.
Iron disulfide is a chemical compound with the chemical formula FeS2. It has a cubic structure which is among the first crystal structures solved by X-ray diffraction.
Aluminum arsenide is a semiconductor material that has almost the same lattice constant as that of gallium arsenide. It can form a superlattice with gallium arsenide which results in its semiconductor properties.
Metal matrix composites (MMCs) are composite materials containing at least two constituent parts – a metal part and a material or a different metal part.
Wrought iron is an iron alloy having a very low carbon content with respect to cast iron. It is soft, ductile, magnetic, and has high elasticity and tensile strength. It can be heated and reheated and worked into various shapes.
Ferrotitanium is a ferroalloy, an alloy of titanium and iron, and sometimes a small amount of carbon. It was first discovered in the year 1798 by W Gregor and was partially purified by H. Moissan in 1895.
The manufacturing and distribution of sportwear is one of the most commercial industries in the world. Footwear is among the more universal items of sports wear reaching a lot of different sports using similar types of sneaker.
Tungsten, a good carbide former, is a steel gray metal that increases temperature and red hardness, prevents gain growth and improves toughness of steels. Tungsten is used in high speed steels and hot forming tool steels.
