Optical study of plasmons in Tl2Ba2Ca2Cu3O10.
TL;DR: The spectral functions of thin films have been determined accurately from combined reflectance and spectroellipsometric measurements.

C-axis infrared response of tl2ba2ca2cu3o10 studied by oblique-incidence polarized-reflectivity measurements
TL;DR: It is shown that from measurements of the reflectivity of a uniaxial medium taken at a finite incidence angle with [ital s]- and [ital p]-polarized light it is possible to determine the dielectric function both parallel and perpendicular to the optical axis.

Normal-state electronic Raman-scattering efficiencies of YBa 2 Cu 3 O 7 − δ , Bi 2 Sr 2 CaCu 2 O 8 , and Tl 2 Ba 2 Ca 2 Cu 3 O 10 : Effects of local-density-approximation Fermi-surface mass fluctuations
TL;DR: The results suggest that anisotropic mass density fluctuations involving various sheets and regions of the Fermi surface are indeed responsible for the electronic Raman continuum and predictable with realistic local-density-approximation band-structure calculations.

TL;DR: In this article, the charge dynamics of high-Tc superconductors with the electric field perpendicular to the planes, using polarized oblique-incidence reflectometry for thin films of Tl2Ba2Ca2Cu3O10 and normal incidence reflectometry, were studied.

Plasmons in high-temperature superconductors
TL;DR: In this article, the low energy part of the dielectric loss function of each system is quadratic with frequency: Im(−1/ϵ) = βω2, nearly up to the screened plasma frequency.
