Abstract
Oxygen impurity in Germanium single crystals has been characterized using Fourier transformed infrared spectrometry. The crystals were grown by Czochralski method in an argon atmosphere. The oxygen concentration in crystals was determined on optical density from the absorption band at 843 cm−1. It was established that oxygen dissolved concentration in Germanium is variable from 0,2·1016 to 1,3·1016 сm−3. The oxygen band maximum shifts toward 856 cm−1 when its concentration increases under the influence of annealing in the oxygen containing atmosphere with ≤ 10−3 Па.
