Growth of Optical Grade Germanium (Ge) Single Crystals by Czochralski Technique

Antimony (Sb) doped Ge crystals are used in the form lenses, windows and prisms in various infrared sensors. Present paper describes the growth of optical grade Ge single crystals by Czochralski technique covering the growth process modification and optimization for growing crystals of different diameters, Sb doping and complete characterization.
