“…Also, the present result is ∼10 ps higher than the calculated bulk positron lifetime in ZnO (154 ps) [7]. Nevertheless, our observation is very close to that of several other groups [7][8][9]14]. Figure 1 represents the ratio of the room temperature CDB spectrum of single crystalline ZnO with respect to the room temperature CDB spectrum of 99.9999 % pure Al.…”

The room temperature positron annihilation lifetime for single crystalline ZnO has been measured as 164 ± 1 ps. The single component lifetime value is very close to but higher than the theoretically predicted value of ∼154 ps. Photoluminescence study (at 10 K) indicates the presence of hydrogen and other defects, mainly acceptor related, in the crystal. Defects related to a lower open volume than zinc vacancies, presumably a complex with two hydrogen atoms, are the major trapping sites in the sample. The bulk positron lifetime in ZnO is expected to be a little less than 164 ps.

“…In the literature there are a number of reports on positron lifetime characterizations in undoped polycrystalline and single crystalline ZnO [6][7][8][9][10]. Some theoretical calculations on bulk and defect related lifetimes also exist in the literature and are summarized in [7].…”
