Enhancement of the UV emission from gold/ZnO nanorods exhibiting no green luminescence
Saskia Fiedler, Laurent O. Lee Cheong Lem, Cuong Ton-That +2
Large reflection losses at interfaces in light emitting semiconductor devices cause a significant reduction in their light emission and energy efficiencies. Metal nanoparticle (NP)…
Strong near-field light-matter interaction in plasmon-resonant tip-enhanced Raman scattering in indium nitride
Emanuele Poliani, Daniel Seidlitz, Maximilian Ries +4
We report a detailed study of the strong near-field Raman scattering enhancement which takes place in tip-enhanced Raman scattering (TERS) in indium nitride. In addition to the wel…
Correlative Study of Enhanced Excitonic Emission in ZnO Coated with Al Nanoparticles using Electron and Laser Excitation
Saskia Fiedler, Laurent O. Lee, Cheong Lem +4
Metal nanoparticle (NP) surface coatings are known to significantly enhance the ultra-violet luminescence intensity of ZnO. Although there is general agreement that resonantly exci…
On thresholdless lasing features in high- nitride nanobeam cavities: a quantum optical study
Stefan T. Jagsch, Noelia Vico Triviño, Frederik Lohof +11
Exploring the limits of spontaneous emission coupling is not only one of the central goals in the development of nanolasers, it is also highly relevant regarding future large-scale…
Molecular nitrogen acceptors in ZnO nanowires induced by nitrogen plasma annealing
C. Ton-That, L. Zhu, M. N. Lockrey +8
X-ray absorption near-edge spectroscopy (XANES), photoluminescence, cathodoluminescence and Raman spectroscopy have been used to investigate the chemical states of nitrogen dopants…
Effects of strain on the valence band structure and exciton-polariton energies in ZnO
Markus R. Wagner, Gordon Callsen, Juan S. Reparaz +6
The uniaxial stress dependence of the band structure and the exciton-polariton transitions in wurtzite ZnO is thoroughly studied using modern first-principles calculations based on…
