Silicon is broadly used in semiconductor and optics. In semiconductor, Si is usually grown by CZ and FZ. Generally, the resistivity of Si grown by CZ(< 10 ohm/cm) is lower than that by FZ(>10 ohm/cm). In infrared optics, we commonly use FZ silicon which is much pure for the purpose of better transmittance. The transmittance is generally between 3-8 um. With AR coatings, the transmittance can reach 95% an...
