I want to know the answer to the following question:
How is hydrogen used in oxide materials?
All the background I'm provided with is that "It is also a potential electron donor in various oxide materials, including ZnO, SnO2, CdO, MgO, ZrO2, HfO2, La2O3, Y2O3, TiO2, SrTiO3, LaAlO3, SiO2, Al2O3, ZrSiO4, HfSiO4, and SrZrO3.". Is that enough to answer the question?
Answer: yes
