Correlation of TEM data with confined phonons to determine strain and size of Ge nanocrystals embedded in SixNy matrix

Bahariqushchi R.; Gündoğdu S.; Aydinli A. (Academic Press, 2017)

Models that use phonon confinement fail to provide consistent results for nanocrystal sizes in differing dielectric matrices due to varying stress experienced by nanocrystals in different dielectric environments. In cases ...
Matrix density effect on morphology of germanium nanocrystals embedded in silicon dioxide thin films

Alagoz, A. S.; Genisel, M. F.; Foss, Steinar; Finstad, T. G.; Turan, R. (Materials Research Society, 2011)

Flash type electronic memories are the preferred format in code storage at complex programs running on fast processors and larger media files in portable electronics due to fast write/read operations, long rewrite life, ...
Spectroscopic ellipsometric study of Ge nanocrystals embedded in SiO 2 using parametric models

Basa, P.; Petrik, P.; Fried, M.; Dâna, A.; Aydinli, A.; Foss, S.; Finstad, T. G. (Wiley - V C H Verlag GmbH & Co. KGaA, 2008)

Ge-rich SiO2 layers on top of Si substrates were deposited using plasma enhanced chemical vapour deposition. Ge nanocrystals embedded in the SiO2 layers were formed by high temperature annealing. The samples were measured ...
