Phonons in layered compounds

Journal of Physics: Condensed Matter, 2001
Layer compounds exhibit highly anisotropic structural and elastic properties. They are characterized by rather rigid layers, loosely stacked together perpendicular to each other. Accordingly, the phonon dispersion of layered compounds are characterized by low lying inter-layer modes and highfrequency intra-layer modes.

Layer-by-Layer polyelectrolyte assemblies for encapsulation and release of active compounds

Advances in Colloid and Interface Science, 2017
Soft assemblies obtained following the Layer-by-Layer (LbL) approach are accounted among the most interesting systems for designing biomaterials and drug delivery platforms. This is due to the extraordinary versatility and flexibility offered by the LbL method, allowing for the fabrication of supramolecular multifunctional materials using a wide range ...

Charge transfer between layers in misfit layer compounds

Journal of Alloys and Compounds, 1995
Electron donation from MX double layers to TX(2) sandwiches, the interlayer bonding and the localization of conduction electrons in misfit layer compounds (MX)(p)(TX(2))(n) (M=Sn, Pb, Sb, Bi, rare earth metals; T=Ti, V, Cr, Nb, Ta; X=S, Se; 1.08 <p <1.23; n = 1,2) are discussed.

Electronic structure of layered compounds

JETP Letters, 2006
The electronic structure of the intercalated graphite compounds XC6 (X = Ca, Sr, Ba, Yb, and La) has been studied using the linearized augmented plane-wave method. It has been found that the electronic structure of the carbon layers in these compounds is qualitatively different from a two-dimensional graphite structure. A lower critical superconducting-

Multi-compound layers in multisensors

Sensors and Actuators B: Chemical, 1992
Abstract Triple compounds with a set of unique functions, and more multicomponent formulae now being explored, may find new applications if we pioneer their use as sensing layers in multisensors.

Synthesis of hexabenzocoronene-layered compounds

Tetrahedron Letters, 2015
Abstract We report herein the synthesis and properties of π-stacked dimeric and polymeric compounds that consisted of hexabenzocoronene (HBC) and xanthene as the stacked π-electron system and the scaffold, respectively; the compounds were obtained by Sonogashira–Hagihara coupling.

Magnetoluminescence in layer compound GaSe

Journal of Magnetism and Magnetic Materials, 1979
Abstract Magnetoluminescence of GaSe is investigated with a split-type superconducting solenoid at 4.2 K up to 10 T. The magnetic field dependence of the spectra between 2.05 and 2.10 eV indicates that most of the sharp lines originate from a complex of a triplet state of an indirect exciton and an ionized impurity.

Restacking Exfoliated Layered Compounds

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1994
Abstract Single-molecular-layer MoS2, prepared by exfoliation of lithium-intercalated MoS2 in water or alcohols, was deposited on supports such as carbon black and alumina. X-ray diffraction patterns show that the stacking of MoS2 layers can be perfectly turbostratic.

Plasma excitation in misfit-layer compounds

Physical Review B, 1992
Plasmons in the misfit-layer compounds MTS 3 (M=Pb, Sn, Bi or Sm; T=Ti, V or Nb), which consist of alternatively stacked MS and TS 2 layers of about 6 A thickness, are studied by means of reflection-electron-energy-loss spectroscopy (REELS). The incident-energy dependence of the excitation energy is investigated by the measurements of the REELS ...
