Deep ultraviolet time-resolved photoluminescence ͑PL͒ spectroscopy has been employed to study Zn-doped AlN epilayers grown by metal-organic chemical vapor deposition. The PL spectra of Zn-doped AlN epilayer exhibited two impurity emission lines at 5.40 and 4.50 eV, which were absent in undoped epilayers and assigned to the transitions of free electrons and(More)
