  • The authors discuss here the complete determination of the elastic properties of polymeric films using two experimental techniques. One technique employs the polymer film as a vibrating membrane and allows a direct determination of the macroscopic biaxial modulus, which serves as a figure of merit of polymer performance in applications such as packaging. Brillouin scattering, which measures the elastic properties on an [approximately] 100-[mu]m scale, allows for a complete characterization of the elastic behavior. Both techniques have been applied to polyimide films. The results obtained by the two techniques are in agreement within the reported error bars.
  • The elastic properties of Mo/Ta superlattices and the dependences on bilayer wavelength over the range 7--200 A are investigated. These are the first such measurements for a bcc-bcc system, and significant differences from previously studied metal superlattices are found. Surface velocities of as many as 12 acoustic modes guided by the thin-film samples have been measured using Brillouin spectroscopy. The elastic constants c/sub 11/,c/sub 13/,c/sub 33/ and c/sub 44/ for the superlattices are determined by fitting the data to an acoustic model of supported hexagonal films. We compare these stiffnesses with those predicted from the bulk constituent properties. The relativemore » Brillouin cross section is found to be accurately represented by a pure ripple scattering theory with no photoelastic contribution.« less
  • The longitudinal (LA) and transverse (TA) Brillouin spectra along [001] phonon direction have been measured as a function of temperature (50--475 K) in single-crystal PbMg{sub 1/3}Nb{sub 2/3}O{sub 3} with scattering angles {theta}{sub {ital s}}=180{degree} and 32.5{plus_minus}0.2{degree}. The Brillouin frequency shift with decreasing temperature shows a broad softening anomaly for both LA and TA phonon modes. For {theta}{sub {ital s}}=180{degree}, a gradual growth in damping with maximum near 270 K is observed and is attributed to order parameter fluctuations. An additional Landau--Khalatnikov maximum is also observed at {ital T}{sub {ital c}}{similar_to}212 K. This anomaly implies a rapid growth of ferroelectric orderingmore » near {ital T}{sub {ital c}} and is consistent with the earlier linear birefringence results reported by Westphal {ital et} {ital al}. The elastic stiffness and compliance constants, {ital C}{sup {ital E}}{sub 11}, {ital C}{sup {ital E}}{sub 44}, and {ital s}{sup {ital E}}{sub 44} are also determined between 200 and 370 K. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.« less
  • The complete sets of elastic constants of 4H and 6H silicon carbide single crystals were determined by Brillouin scattering. The elastic constants of 6H SiC are C{sub 11}=501{plus_minus}4, C{sub 33}=553{plus_minus}4, C{sub 44}=163{plus_minus}4, C{sub 12}=111{plus_minus}5, and C{sub 13}=52{plus_minus}9GPa; the corresponding ones of 4H SiC are the same within experimental uncertainties. The compressibility, 4.5{times}10{sup {minus}3}GPa, is about 3{endash}5 times smaller than those reported for polycrystalline SiC materials. {copyright} {ital 1997 American Institute of Physics.}
