Calibration factor for determination of interstitial oxygen concentration in germanium by infrared absorption
(2005) In Solid State Phenomena 108-109. p.735-740- Abstract
- Intensities of infrared absorption due to asymmetric stretching vibrations of interstitial oxygen atoms in Ge crystals enriched with O-16 and O-18 isotopes have been compared with oxygen concentrations determined by means of secondary ion mass spectrometry (SIMS). For Ge samples with oxygen content less than 510(17) cm(-3) a good correlation has been found between the values of oxygen concentration and values of absorption coefficient in maximum of the absorption band at 855.6 cm(-1) with a proportionality coefficient C-O = 0.95 10(17) cm(-2). It is argued that kinetics of oxygen-related thermal double donor formation and oxygen loss upon heat-treatments of Ge crystals at 350 degrees C cannot be described properly with the application of...
