DOI: 10.1063/1.4974366

Abstract: The temperature dependence of Raman shifts for different layers and different optical phonon modes in an AlGaN/GaN stack was examined in this study. The slopes of the Raman shifts as a function of temperature for… read more here.

DOI: 10.1080/01411594.2019.1566544

Abstract: ABSTRACT The temperature dependence of the Raman active frequencies of the lattice modes of dibromocubane is measured below room temperature. The frequencies are linearly dependent on the temperature decreasing with increased temperature with a marked… read more here.

DOI: 10.1134/s1063776120090150

Abstract: The angular dependence of Raman scattering intensity in silicon nanocrystals has been measured. Silicon nanocrystals have been fabricated by annealing of a silicon layer amorphosized by ion implantation and can therefore be formed only in… read more here.

DOI: 10.1364/oe.518356

Abstract: We report on micro-Raman spectra of several mixed laser ceramics, i.e., 5at.%Tm:(ScxY1-xO2)3 with x = 0.121, 0.252, 0.489 and 5at.%Tm:Y2O3 ceramic. The samples were fabricated by solid-state pressureless consolidation of nanopowders produced by laser ablation of solid… read more here.
