Аннотация: The annealing effect in the temperature range from 350 to 450 degrees C on the behavior of interstitial oxygen O-i. dissolved in germanium and on optical properties of single crystals has been investigated by Fourier transformed infrared spectrometry. It was found that oxygen band maximum of 843 cm(-1) shifted toward the 856 cm(-1)Показать полностьюwith oxygen concentration increasing after annealing at the oxygen partial pressure ranged from 1 to 10(3) Pa. The annealing at lower P-O2 values led to the decrease of 843 cm(-1) band intensity due to the formation of thermal donors (TD) on the basis of dissolved oxygen atoms O-i. It was established that TD formation and the decrease of unbound oxygen concentration affected optical properties of the crystals.
