Core level photoabsorption study of defects and metastable bonding in boron nitride
- Lawrence Livermore National Lab., CA (United States); and others
A comprehensive study of different bonding environments and defect structure in boron nitride films and materials has been performed using core level photoabsorption. We have identified nitrogen vacancies in the hexagonal bonding of BN, nitrogen interstitials, boron clustering, sp3 like metastable phases and sp3 phases in BN films grown by various methods. Quantitative information on the concentration and distribution of point defects can be determined and is directly related to the formation of new phases. The characterization of thin films using the chemically selective technique of synchrotron radiation based core level photoabsorption can overcome the limitations of other structural probes.
