Correlation of TEM data with confined phonons to determine strain and size of Ge nanocrystals embedded in SixNy matrix
(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 ... -
Ge nanocrystals embedded in ultrathin Si3N4 multilayers with SiO2 barriers
(Academic Press, 2017)Multilayers of germanium nanocrystals (NCs) embedded in thin films of silicon nitride matrix separated with SiO2 barriers have been fabricated using plasma enhanced chemical vapor deposition (PECVD). SiGeN/SiO2 alternating ... -
Optical bandgap of semiconductor nanostructures : Methods for experimental data analysis
(American Institute of Physics Inc., 2017)Determination of the optical bandgap (Eg) in semiconductor nanostructures is a key issue in understanding the extent of quantum confinement effects (QCE) on electronic properties and it usually involves some analytical ... -
Size controlled germanium nanocrystals in dielectrics : structural and optical analysis and stress evolution
(Bilkent University, 2017-08)Group IV semiconductor nanocrystals, namely silicon and germanium have attracted much interest in the past two decades due to their broad applications in photovoltaic, memory, optoelectronic, medical imaging and ...
