Hydrogen Donors in Anatase TiO2 [PDF]
physica status solidi (b), 2021 Two hydrogen‐related donors in anatase —interstitial hydrogen () and hydrogen substituting for oxygen ()—are addressed by means of ab initio density functional theory and vibrational mode spectroscopy. First‐principles calculations and infrared (IR) absorption measurements reveal that forms an OH bond lying in the basal plane of the crystal ...
