Journal ArticleDOI
Neutral-donor–bound-exciton complexes in ZnO crystals
Donald C. Reynolds,David C. Look,B. Jogai,Cole W. Litton,T. C. Collins,W. C. Harsch,G. Cantwell +6 more
TL;DR: In this article, the neutral-donor bound excitons were observed in the form of rotator states analogous to rotational states of the ${\mathrm{H}}_{2}$ molecule.
Journal ArticleDOI
High-Quality, Melt-Grown ZnO Single Crystals
D. C. Reynolds,Cole W. Litton,David C. Look,J. E. Hoelscher,Bruce B. Claflin,T. C. Collins,Jeff Nause,B. Nemeth +7 more
TL;DR: In this paper, the intrinsic properties associated with the wurtzite structure of the ZnO crystals were investigated and compared with the same spectra from high-quality, vapor-grown ZnOsO crystals.
Journal ArticleDOI
Photoluminescence measurements from the two polar faces of ZnO
R. E. Sherriff,D. C. Reynolds,David C. Look,B. Jogai,J. E. Hoelscher,T. C. Collins,G. Cantwell,W. C. Harsch +7 more
TL;DR: In this paper, the crystal structure of ZnO is wurtzite and the stacking sequence of atomic layers along the “c” axis is not symmetric.
Journal ArticleDOI
Polariton and Free-Exciton-Like Photoluminescence in ZnO
TL;DR: In this article, an unusual photoluminescence line X has been observed in ZnO at an energy between that of the common donor-bound excitons (DBEs) and the free exciton (FEs).
