Journal ArticleDOI
Electrical properties of bulk ZnO
David C. Look,Donald C. Reynolds,J. R. Sizelove,R. L. Jones,Cole W. Litton,G. Cantwell,W. C. Harsch +6 more
TL;DR: In this paper, large diameter (2-inch) n-type ZnO boules were grown by a new vapor-phase transport method using temperature-dependent Hall-effect technique.
Journal ArticleDOI
Valence-band ordering in ZnO
TL;DR: In this paper, the emission and reflection spectra of ZnO have been investigated in the intrinsic region and the data have been interpreted in terms of the wurtzite crystal band structure.
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
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
Optical properties of ZnO crystals containing internal strains
Donald C. Reynolds,David C. Look,B. Jogai,R. L. Jones,Cole W. Litton,W. C. Harsch,G. Cantwell +6 more
TL;DR: In this article, the authors show how stress changes during the annealing process can be used to develop a model that explains the origin of emission lines at 3.2898 and 3.2176 eV.
