Journal ArticleDOI
Critical properties of nanoporous low dielectric constant films revealed by Brillouin light scattering and surface acoustic wave spectroscopy
TL;DR: In this article, Brillouin light scattering and surface acoustic wave spectroscopy are used to measure density, porosity and stiffness properties of nanoporous methylsilsesquioxane films of low-k value.
Journal ArticleDOI
Elastic properties of thin h-BN films investigated by Brillouin light scattering
TL;DR: In this paper, the elastic properties of the films grown on silicon substrates under identical coating conditions have been de-termined by Brillouin light scattering from thermally excited surface phonons.
Journal ArticleDOI
Elastic properties of indium tin oxide films
TL;DR: In this article, a series of DC sputtered ITO films with thicknesses ranging from 31 to 3600 nm were deposited at a substrate temperature of 1508C on hydrogen terminated (100) silicon.
Journal ArticleDOI
Brillouin light scattering from surface phonons in hexagonal and cubic boron nitride films
TL;DR: In this paper, the phase velocities of surface acoustic waves in several boron nitride films were investigated by Brillouin light scattering, and four independent elastic constants were determined from the dispersion of the Rayleigh and the first Sezawa mode.
Journal ArticleDOI
Brillouin light scattering study on the elastic properties of thick sputtered c-BN films
TL;DR: In this article, the Brillouin light scattering technique is used to observe thermally excited acoustic phonons in backscattering geometry in a transparent, 1.8 μm thick diode sputtered c-BN film.
