Conjugated semiconducting block copolymers are interesting organic materials for possible photovoltaic device applications because of their capability to form self-organized nanostructures and the tunability of their electronic and optical properties

When viewed at frequencies below about 8 THz (250 cm-1; 30 meV) the ab-plane optical conductivity of the cuprate superconductors (in their normal state) is well described by a Drude model. Examples include optimally-doped YBa2Cu3O7-δ and Bi2Sr2CaCu2

In clean metallic superconductors, 100% of the mobile carriers participate in the condensate, so that the London penetration depth (which measures the electromagnetic screening by the superconductor) indicates charge densities comparable to those inf

The temperature (6{endash}350 K) and magnetic-field dependence (0{endash}7.5 T) of the phononic Raman spectra in the layered manganites, R{sub 1.2}Sr{sub 1.8}Mn{sub 2}O{sub 7} (R=La,Nd), reveal anomalous behaviors of the Mn and equatorial O{sub xy}{s

Polarized Raman spectra of undoped and doped ${\mathrm{La}}_{1\ensuremath{-}x}{M}_{x}{\mathrm{MnO}}_{3}$ single crystals have been studied in the temperature range from 5 to 423 K ($M=\mathrm{Sr},$ Ca). The spectral intensity is mainly related to sca

We report polarized Raman spectra of La1−xSrxMnO3 crystals (x = 0, 0.1, 0.2 and 0.3) in the temperature range from 5 K to 300 K. The small distortion of the nearly cubic lattice of doped La1−xSrxMnO3 single crystals results in a structured phonon

The temperature dependent infrared conductivities of Bi2Sr2CaCu2O8 (Tc ⋍ 82 K) and Bi2Sr2CuO6 (Tc ⪅ 5 K) are compared with non-Fermi liquid approaches to the normal state of the high Tc superconductors. We find reasonable agreement with our data
