Electronic structure and spontaneous polarization in multiferroic bulk BiFeO 3 Z. Mahhouti 1,2,3,* Â, H. El Moussaoui 1, M. Hamedoun 1, M. El Marssi 3, A. Lahmar 2, A. El Kenz 2,Â and A. Benyoussef 1,2,4 Abstract: The electronic structure, magnetic properties and spontaneous polarization in Bismuth ferrite BiFeO 3 are investigated using first-principle calculations. Due to the complexity and insufficiency of microscopic descriptions of the crystal structures and morphologies of the blend of two polymers known as PEDOT:PSS, most studies on its electronic structure are based on experimental data complemented with quantum chemical calculations to predict both the geometrical and crystal structures and compute the electronic band structure.

The bottom two spectra are the absorbance spectra of the solutions. Diffuse reflectance spectra obtained on ground crystals of the solids and optical absorbance spectra of the solutions for the aquo and acetonitrile complexes are nearly superimposable, but each feature in the spectrum of the acetonitrile complex is red-shifted by approximately.

Ichiro Tanabe, Yukihiro Ozaki. Summary. Unpolarized specular reflectance spectra at near-normal incidence were measured in the silicates olivine, pyroxene, spinel and Al-garnet in the photon energy range 4–14 eV at °K, and the optical and dielectric functions were obtained from the reflectance by Kramers-Kronig analysis.
Rubloff, G.W., Far-Ultraviolet Reflectance Spectra and the Electronic Structure of Ionic Crystals, Phys. Rev. B: Solid State,vol. 5, no. 2, pp. – The optical reflectance spectra of alkali halide crystals KI and RbI were measured over the energy range of to eV. Both single crystal and poly-crystal samples were used to accomplish this task.
The phase θ (ω) was computed using the Kramers-Kronig relation between the real and imaginary parts of the complex function, ln r = ln | r | + i θ (ω). Subsequently, the optical. Controllably tuned infrared emissivity has attracted great interest for potential application in adaptive thermal camouflage.
In this work, we report a flexible multilayer graphene based infrared device on a porous polyethylene membrane, where the infrared emissivity could be tuned by ionic liquid intercalation.
The Fermi level of surface multilayer graphene shifts to a high energy level. Donald S.

The changes in lattice and electronic structures of 2H- 4H- and 6H-SiC polytypes at room temperature were investigated when pressures from 10 GPa to GPa were applied. It’s found that the applied pressures didn’t cause a change in the hexagonal structure of the crystals, however the structural and electronic properties clearly affected.
The following properties are discussed: crystal structure, optical and dielectric properties, dielectric constant and loss angle, electric and thermal conductivity, transport phenomena in magnetic fields, magnetic and scattering phenomena, x-ray properties, and thermodynamic properties.
