Development of High Spectral Resolution Technique for Registration Quasielastic Light Scattering Spectra Including Rayleigh and Brillouin Scattering as a Diagnostic Tool in Materials Characterization
ABSTRACT
This report results from a contract tasking Ioffe Physico-Technical Institute as follows: As detailed in an on-line proposal
the contractor will: 1) develop and build an optical device, fitted to a Fabry-Perot interferometer, to perform high-resolution
quasieleastic light scattering spectroscopy; 2) develop related techniques for registering quasieleastic laser light scattering
spectra; 3) measure temperature-dependent (77-300 degrees Kelvin) electrical conductivity to characterize metal/polymer/
metal systems; 4) perform high-resolution Raman scattering mapping of epoxy/Al and teflon/Al interfaces to find quasalelastic
scattering and the evolution of structural changes; 5) perform Brillouin light-scattering measurements on epoxy/Al and
teflon/Al interfaces for evolution of the longitudinal modulus from the surface of polymer close to polymer/Al interfaces; 6)
perform Rayleigh and quasielastic light scattering measurements on epoxy/Al. epoxy/Ag and teflon/Al interfaces to find the
evolution of the relaxation time from the surface of polymer close to polymer/metal interfaces.
