Germanium single crystal wafers are an important semiconductor substrate material. These high-quality substrates are primarily used in CPV, outer-space solar-cell panel and high-bright light-emitting diode applications.
OST Photonics offers Low EPD (etch pit density) or even Zero EPD Ge wafers for semiconductor industry, germanium wafers are supplied in diameters from 2" to 6" with resistivity from 0.005 ohm.cm to over 50 ohm.cm. Monocrystalline Ge wafers are an important semiconductor material. High quality Ge substrates are used in Concentrator Photovoltaic power stations (CPV), outer-space solar cell panels and ultra-high brightness LEDs. In addition, customized germanium substrates also are available upon request.
