Journal ArticleDOI
Bound exciton and donor–acceptor pair recombinations in ZnO
Bruno K. Meyer,H. Alves,Detlev M. Hofmann,W. Kriegseis,D. Forster,Frank Bertram,Jürgen Christen,Axel Hoffmann,M. Straßburg,M. Dworzak,U. Haboeck,Anna V. Rodina +11 more
TL;DR: In this paper, the optical properties of excitonic recombinations in bulk, n-type ZnO are investigated by photoluminescence (PL) and spatially resolved cathodoluminecence (CL) measurements.
Journal ArticleDOI
Hydrogen: A Relevant Shallow Donor in Zinc Oxide
Detlev M. Hofmann,A. Hofstaetter,F. Leiter,Huijuan Zhou,Frank Henecker,Bruno K. Meyer,Sergei Orlinskii,Jan Schmidt,Pavel G. Baranov +8 more
TL;DR: Using electron nuclear double resonance it is found that D1 shows hyperfine interaction with more than 50 shells of surrounding 67Zn nuclei, proving that it is a shallow, effective-mass-like donor.
Journal ArticleDOI
The Oxygen Vacancy as the Origin of a Green Emission in Undoped ZnO
TL;DR: In this article, the authors investigated undoped ZnO single crystals, which are commercially available from Eagle-Picher, by photoluminescence (PL) and optically detected magnetic resonance (ODMR) spectroscopy.
Journal ArticleDOI
Behind the weak excitonic emission of ZnO quantum dots: ZnO/Zn(OH)2 core-shell structure
Huijuan Zhou,H. Alves,Detlev M. Hofmann,W. Kriegseis,Bruno K. Meyer,G. Kaczmarczyk,Axel Hoffmann +6 more
TL;DR: The structure of ZnO quantum dots prepared via the wet chemical method was studied in this article, and the effect of the change in the structure of the dots on their luminescence properties was investigated.
Journal ArticleDOI
Assessing the structural properties of graphitic and non-graphitic carbons by Raman spectroscopy
Dominique B. Schuepfer,Felix Badaczewski,Juan Manuel Guerra-Castro,Detlev M. Hofmann,Christian Heiliger,Bernd M. Smarsly,Peter J. Klar +6 more
TL;DR: In this paper, the transformation from molecular to crystalline of (non-)graphitic carbons synthesized from organic precursors by heat-treatment is studied, and Raman spectroscopy, in particular, the Raman lineshape analysis of G and D mode, offers quick assessment of the average sheet size of such carbons.
