Charge Density Waves in Layered Compounds

Surface Science, 1976
This conference concerns the properties of “One Dimensional” metals. However, I’m going to talk about Charge Density Wave (CDW) states in two dimensional metals. The motive for doing that at this conference is that there are a number of similarities in the kinds of phenomena that occur in the one and two dimensional systems and in the theories proposed

Layer rigidity and spacing in intercalation compounds

Physical Review B, 1989
A generalization of Vegard's law for the average spacing between layers when atoms with different sizes are intercalated is derived. New parameters are introduced that describe the layer rigidity associated with ``catchment areas'' around the large ions.

Photoelectromagnetic effect in layered compounds

Il Nuovo Cimento B Series 11, 1977
Photoconductivity (PC), photovoltaic and photoelectromagnetic (PEM) measurements are a very useful method for transport parameter investigation, particularly when the high resistivity of the materials makes difficult direct measurements. We have applied these effects to determine some transport parameters (τ,L) of the layered compounds GaSe, PbI2, HgI2

Madelung constants for layer compounds

Journal of Physics C: Solid State Physics, 1983
Madelung constants have been calculated for layer compounds having octahedral and trigonal prismatic coordination structures, the value being 12.3 and 10.2 respectively. Applying the results to TaS2, it was found that Ta ions carry a charge of about 1.2e.

Surface superconductivity in layered compounds

Soviet Journal of Low Temperature Physics, 1977
The features of surface superconductivity onset in layered superconductors with Josephson and correlation layer interactions are studied. It is shown that in comparison with ordinary type-II superconductors the situation in layered compounds is more complicated.

Superconductivity in the layered compound LixNbO2

Nature, 1990
SEVERAL classes of copper oxide compounds are high-temperature superconductors1–3; the highest known transition temperature (Tc) is 122 K for Tl2Ba2Ca2Cu3O11 (ref. 4). Superconductivity has also been observed in oxides containing early transition metals, but the superconducting transition temperatures are substantially lower.

Investigation of the layered compound Fe0.5Cd0.5PS3

Journal of Physics and Chemistry of Solids, 1992
Abstract The homocharge substituted compound Fe 0.5 Cd 0.5 PS 3 of the MPS 3 family was prepared from parent compounds FePS 3 and CdPS 3 . Powder XRD studies reveal the formation of a substituted homogeneous compound with a cell volume intermediate between those of FePS 3 and CdPS 3 . 57 Fe Mossbauer investigation was undertaken to determine the

Photoluminescence of the layered compound CdInGaS4

Il Nuovo Cimento D, 1983
The photoluminescence of the layered compound CdInGaS4 was measured and analysed. The broad emission band at about 1.95 eV was found to be composed of three bands peaking at 2.16, 1.98 and 1.76 eV at 4.8K. These bands are due to free-to-bound or donor-to-acceptor transitions. We have found a new emission band peaking at 2.38 eV.

Optical anisotropy in layer compounds

Journal of Physics C: Solid State Physics, 1973
Normal incidence reflectivity spectra using polarized light have been measured with E perpendicular to c as well as E//c for the layer type crystals of transition metal dichalcogenides WS2, WSe2, alpha -MoTe2, NbS2 and NbSe2 at 78 K and 300 K. Reflectivity peaks observed in the spectra of two polarizations are derived from transitions of quite ...

Intercalation Reactions of Layered Compounds

1992
Abstract Intercalation reactions are reactions of solids in which a guest molecule or ion is inserted into a solid lattice without major rearrangement of the solid structure. Unlike normal solid state processes, intercalation reactions do not involve extensive bond breaking and consequently require special chemical and structural ...
