  • Composition comprising an engineered defect concentration
    Patent number: 10161062
    Abstract: A composition comprising an engineered defect concentration comprises a metal oxide single crystal having a polar surface and a bulk concentration of interstitial oxygen (Oi) of at least about 1014 atoms/cm3. The polar surface comprises a concentration of impurity species of about 5% or less of a monolayer. A method of engineering a defect concentration in a single crystal comprises exposing a metal oxide single crystal having a polar surface to molecular oxygen at a temperature of about 850° C. or less, and injecting atomic oxygen into the single crystal at an effective diffusion rate Deff of at least about 10?16 cm2/s.
    Type: Grant
