摘要：

Hydrogen defects in single-crystalline SnO2 are studied by combined photoconductivity and IR absorption spectroscopy. Our results indicate that a defect with an O-H local vibrational mode at 3272 cm(-1) (10 K) is a donor with a level less than 300 meV below the conduction band. Annealing experiments demonstrate that the defect is stable up to approximately 450 degrees C and therefore may contribute to persistent n-type conductivity of SnO2.
