The authors of our Editor's Choice [1] investigate ZnO nanorods by means of time resolved spectroscopy. Resonator and waveguide properties as well as the influence of gold nanoparticles at the nanorod/substrate interface are evaluated using numerical simulations. Part a) of the cover figure shows the intensity distribution of the electric field. As demonstrated in the right part of a), a higher refraction index step at the interface gold/GaN leads to an improved light confinement. Part b) is the cross section perpendicular to the growth direction, and c) a TEM picture of the interface with gold particles appearing as dark droplets. The first author Robert Hauschild is currently a member of the Graduate College “Collective Phenomena in Solids” to pursue a Ph.D. at the University of Karlsruhe (TH). Among his research interests are the optical properties of nano‐ and mesoscopic systems, including excitonic processes in ZnO nanorods and waveguides. This issue of physica status solidi (b) contains a collection of articles presented at The Twelfth International Conference on II–VI Compounds held in Warsaw, Poland, 12–16 September 2005. Further papers from II–VI 2005 are published in phys. stat. sol. (c) 3 , No. 4 (2006).
