Polarized terahertz transmittance and infrared reflectivity measurements were performed on selected lead zirconate crystals at T = 10 K. The fit of the spectra enabled us to obtain all three principal components of its anisotropic dielectric function

Amorphous SiCxNy films (of 2.2–2.7 μm) were deposited on Si(111) substrates by reactive DC magnetron sputtering. The SiC target with small excess of carbon was sputtered at various N2/Ar gas flow ratios (0–0.48). The as-deposited films were addi

The anisotropy of the dielectric function of c -axis oriented MgB 2 thin films has been revealed by a combined study of normal-incident reflectance and spectroscopic ellipsometry. The application of this procedure enabled us to determine the complete

Broad-band dielectric responses (10 2 -10 14 Hz) of Sr 1-1.5x Bi x TiO 3 (x=0.0067÷0.133) ceramics and K 1-x Li x TaO 3 (x=0.050÷14) single crystals are analysed and compared. The common features are emphasized: softening of the polar phonon is sup

Physica C: Superconductivity. 362:86-91
Anomalous spectral behavior of the c-axis far-infrared conductivity at low-temperatures has been investigated in high-Tc superconducting cuprates (HTSC). As the temperature is lowered, a broad bump grows around 450 cm−1 and the in-plane oxygen phon

Infrared reflectivity spectra of lead zirconate ceramics were measured in the frequency region of 20-3000 cm-1 and temperature range from 10 to 900 K. The data, extended to lower frequencies by coherent source submillimetre, time-domain terahertz tra

Molecular beam epitaxy has been used to grow epitaxial layers of different CuIn x Se y phases on (111) oriented silicon substrates. Rutherford backscattering channeling yields of 7-11% and X-ray rocking curve linewidths of 900 arcsec measured for 600

The optical spectra of some high-Tc cuprates show anomalous bump around 450 cm−1and dramatic phonon changes for E parallel to c axis, which grows at low temperatures. This phenomenon has been observed in Yba2Cu3O6.6, YBa2Cu4O8and Pb2Sr2RCu3O8, but
