Excitonic Fine Structure in Emission of Linear Carbon Chains

Fine structure in the excitonic emission of InAs/GaAs quantum dot molecules

The exciton fine structure in self-assembled coupled quantum dots with barriers of varying widths is studied in detail. For narrow barriers we find doublet splittings of the molecule ground state exciton in magnetic field, while for wide barriers in some cases a multiplet of emission lines is observed. Pronounced anticrossings occur in the field dispersion of such a multiplet with details depen...

Excitonic fine structure and binding energies of excitonic complexes in single InAs quantum dashes

The fundamental electronic and optical properties of elongated InAs nanostructures embedded in quaternary InGaAlAs barrier are investigated by means of high-resolution optical spectroscopy and many-body atomistic tight-binding theory. These wire-like shaped self-assembled nanostructures are known as quantum dashes and are typically formed during the molecular beam epitaxial growth on InP substr...

Excitonic fine structure and recombination dynamics in single-crystalline ZnO

the role of thematic structure in comprehending spoken language

in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...

Developing Very Fine Nanopearlitic Structure in a High Carbon Steel Wire before Drawing

The effects of steel wire patenting process parameters on very fine interlamellar spacing in the pearlitic steel wire were investigated and the optimized condition of the process was achieved. In this work, the initial nanopearlitic structure was obtained in a 0.72 wt% carbon steel wire before the wire drawing process. The results were the minimum interlamellar spacing of 35 nm and maximum ulti...
