- Abstract (EN)
- Oxygen in single crystalline antimony triselenide (Sb₂Se₃) is addressed by infrared (IR) absorption spectroscopy. Measurements conducted on Sb₂Se₃ samples doped—during growth, post-growth annealing in the O₂ ambient, or by O ion implantation—with ¹⁶O reveal an IR absorption line at 527 cm⁻¹ (10 K). Substitution of ¹⁶O by ¹⁸O “red”-shifts the signal down to 500 cm⁻¹ based on which the line is assigned to a local vibrational mode of an isolated oxygen defect. Annealing of O-enriched samples in hydrogen atmosphere at temperatures above 380 °C results in the suppression of the 527-cm⁻¹ line and concurrent appearance of the signals due to hydroxyl groups, suggesting formation of oxygen-hydrogen complexes. The configuration of the 527-cm⁻¹ oxygen center is discussed.
