(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)We have used depth-resolved cathodoluminescence, positron annihilation, and surface photovoltage spectroscopies to determine the energy levels of Zn vacancies and vacancy clusters in bulk ZnO crystals. Doppler broadening-measured ...
