Depth-resolved optical studies of excitonic and phonon-assisted transitions in ZnO epilayers
15th Nov 2006, 00:07 GMT
Yong-Hoon Cho, Ji-Young Kim, Ho-Sang Kwack, Bong-Joon Kwon, Le Si Dang et al. The authors report depth-resolved optical properties of excitonic and phonon-assisted transitions in ZnO epilayers by photoluminescence (PL) and cathodoluminescence. A weaker free exciton (FX) emission than its first longitudinal optical phonon replica (FX-1LO) is observed at elevated temperatures ( ... [Appl. Phys. Lett. 89, 201903 (2006)] published Tue Nov 14, 2006.
