Revisiting the configurations of hydrogen impurities in SrTiO3: Insights from first-principles local vibration mode calculations
Cai Zenghua, Ma Chunlan
The specific configurations of hydrogen impurities in SrTiO3 (STO) are still ambiguous. In this study, we systematically investigate the configurations and vibrational properties o…
