Influence of Ge content and annealing conditions on the PL properties of nc-Si1-xGex embedded in SiO2 matrix in weak quantum confined regime
Tuğay, Evrin; İlday, Serim; Turan, Raşit; Finstad, Treje G. (Elsevier Science Bv, 2014)Fabrication of Si (nc-Si), Ge (nc-Ge), and Si1-xGex (nc-Si1-xGex) nanocrystals embedded in SiO2 matrix is achieved by thermal annealing of magnetron-sputtered thin films. Effects of annealing conditions, namely duration ... -
Investigation of photoluminescence mechanisms from SiO2/Si:SiO2/SiO2 structures in weak quantum confined regime by deconvolution of photoluminescence spectra
Tuğay, Evrin; Turan, Raşit (Amer Scientific Publishers, 2016)Si nanocrystals embedded in SiO2 matrix were prepared by co-sputtering method followed by a post annealing process in N-2 ambient. By fixing sputtering parameters, the effects of annealing time and annealing temperature ... -
Temperature-dependent optical properties of GaSe layered single crystals
Işık, Mehmet; Tuğay, Evrin; Hasanlı, Nizami (Taylor & Francis Ltd, 2016)Optical properties of GaSe single crystals have been investigated using temperature-dependent transmission and room temperature reflection measurements in the wavelength range of 380-1100nm. the analysis of the absorption ... -
Temperature-tuned band gap energy and oscillator parameters of GaS0.5Se0.5 single crystals
Işık, Mehmet; Tuğay, Evrin; Hasanlı, Nizami (Elsevier Gmbh, Urban & Fischer Verlag, 2016)Temperature-dependent transmission and room temperature reflection measurements were carried out on GaS0.5Se0.5 single crystal in the wavelength range of 380-1000 nm to investigate its optical parameters. the analysis of ...
