Isotopic study of the nitrogen-related modes in N+-implanted ZnO Martil De La Plaza, Ignacio González Díaz, Germán Micro-Raman measurements were performed to study the nitrogen-related modes in ZnO samples implanted with N+. The two stable N isotopes, N-14 and N-15, were implanted. Distinct peaks at 277 and 512 cm(-1) are observed irrespective of the implanted isotope, both before and after rapid thermal annealing. The insensitivity of the mode frequencies to the implanted isotope rules out the explanation of these modes as local vibrational modes involving N motion. These modes were not detected in ZnO samples implanted with Zn+, O+, or P+, which suggests that they may be associated with distortions/defects favored by the presence of N. 2023-06-20T10:44:11Z 2023-06-20T10:44:11Z 2023-06-20T10:44:11Z 2007-04-30 journal article https://hdl.handle.net/20.500.14352/51109 0003-6951 10.1063/1.2734474 eng MAT2004-0664 open access Amer Inst Physics
