“…There have been many CdS deposition techniques including vacuum evaporation (Grynko et al, 2009), RF sputtering (Akkad and Ashour, 2009), chemical vapor deposition (Jones et al, 2009) and molecular beam epitaxy (Ueta et al, 2000). All these methods require special tools, and therefore their manufacturing cost is high.…”

“…1(a). Nine ZnS pyramids with the square bottom sizes of 100-900 nm each separated by 100 nm were selectively grown on the DBR surface with MOMBE [8]. The reflection spectra of the ZnS pyramids were measured with a microreflection measurement set-up with the spatial resolution of ~1 µm.…”

PACS 78.66.Hf, Pyramidal microcavities coupled to distributed feedback reflectors (DBRs) substantially modified the DBR stop-bands and the physical origin was theoretically studied. This was attributed to the change of the DBR surface reflection phases with the formation of the pyramidal structures. The theoretically predicted variation of the reflection spectra was qualitatively reproduced with the reflection measurements on the DBR where ZnS pyramids were formed on the surface. Based on these examinations, the increase of the DBR periods is proposed to realize more stable DBR operations against the formation of the pyramids on its surface.

Published online zzz 7 PACS 78.55. Et, 42.50.Ct 8 Dynamical properties of exciton localization into spatially isolated localized states with atom-like density of states 9 caused by alloy potential fluctuations were examined. Submicron-sized mesa-shaped structures were prepared to 10 resolve the contribution of single localized states to the optical spectra, which makes it possible to observe atom-like 11 emission lines and to discuss the dynamical properties of exciton energy relaxations by employing micro-time-12 resolved PL measurements. It will be shown that in the samples with high exciton energy transfer efficiency, photo-13 generated excitons can relax into the spatially isolated localized centers with strong zero-dimensional nature, which 14 leads to the limited number of atom-like emission lines. 15
