Profile: Huizhou Tian Yi Rare Material Co.,Ltd offers sputtering targets, semiconductor materials, rare earth materials and crystal materials. Semiconductor materials are insulators at absolute zero temperature that conduct electricity in a limited way at room temperature. The defining property of a semiconductor material is that it can be doped with impurities that alter its electronic properties in a controllable way. The most commonly used semiconductor materials are crystalline inorganic solids. Our semiconductor materials include indium arsenide, tin arsenide, aluminum nitride, boron nitride, aluminum phosphide, gallium phosphide, cadmium selenide, zinc selenide, lead selenide and indium selenide.
