Optical properties of silicon nanocrystallites in SiO2 matrix: Crystalline vs. amorphous case / R. Guerra, I. Marri, R. Magri, L. Martin Samos, O. Pulci, E. Degoli, S. Ossicini. - In: SUPERLATTICES AND MICROSTRUCTURES. - ISSN 0749-6036. - 46:1-2(2009), pp. 246-252. [10.1016/j.spmi.2008.10.020]
Abstract:
Within a first-principles framework we show the dependence of the optical properties of silicon nanocrystallites embedded in a silica matrix on the crystalline vs. amorphous order of the system. Moreover we calculate how many-body effects modify the electronic and optical properties of the embedded silicon nanodots. A discussion about the different roles played by dimensionality, interface properties, disorder and excitonic effects on the electronic and optical properties of the confined nanostructures is presented.
