Germanium (Ge)
Germanium_targetGermanium is a grayish-white metalloid which is brittle and crystalline. Electrically it behaves as a semiconductor. Its chemistry is similar to that of silicon, and it has applications as an alternative to silicon as a basis for solid state electronic devices.
As a usually thin film material, Germanium targets are used more and more widely. The shape includes disk, sheet, tube, step, taper and so on. Also we can make some hole and screw  on the target base on your require. The surface is very beautiful. They are used in  widely optics , electron ,decorate, and so on. Germanium is a usually metal, It was used widely in I.R. optical , electronical,  decorative ...field.
