Band structure of lead sulphide

Journal of Physics: Condensed Matter, 1992
The band structure of lead sulphide has been investigated using angle-resolved photoemission, with synchrotron radiation in the photon energy range 25-95 eV as the excitation source. Many spectral features originate from direct transitions, while others are due to 'density of state' features, i.e.

Bulk band structure of chromium

Physical Review B, 1986
The bulk band structure of paramagnetic chromium, calculated with use of the linear augmented plane-wave method, is presented and discussed. The calculated band structure is used for interpreting the data obtained in angle-resolved photoemission experiments carried out on Cr(110).

G-banding and chromosome structure

Chromosoma, 1973
G-banding of chromosomes promises to be the most valuable technique for routine chromosome analysis due to its inherent simplicity, sensitivity, and stability of the material obtained. In the past, banding procedures have had several shortcomings in regard to efficiency and consistency of results.

Banded structures in cauda equina

Pathology, 1975
Banded structures identified in a cauda equina biopsy from a patient with compression are identical to those seen in schwannomas and several other conditions and identified as fibrous long-spacing collagen. They are present in relation to the basement membrane with a periodicity of about 1200 A.

Energy Band Structures of Semiconductors

2001
The physical properties of semiconductors can be understood with the help of the energy band structures. This chapter is devoted to energy band calculations and interpretation of the band structures. Bloch theorem is the starting point for the energy band calculations.

Energy Band Structure of Proteins

Nature, 1964
FOR the interpretation of transfer of energy in proteins, Szent-Gyorgyi suggested the possibility of conductivity in these molecules1. Laki2, in order to interpret the effect of neutral salts on the isoelectric point of casein, has assumed that there was an electronic delocalization through the hydrogen bonds of proteins and has suggested taking the H ...

Energy Band Structure of Graphite

IBM Journal of Research and Development, 1964
The energy band structure of graphite is described in the region of the Fermi surfaces by the Slonczewski-Weiss model. The electron and hole Fermi surfaces are highly elongated and are aligned along the six Brillouin zone edges which are parallel to the trigonal axis of the crystal.

Band Structure of White Tin

Physical Review, 1963
A perturbation calculation of the band structure in white tin is performed using the orthogonalized plane wave approximation. The energies are determined for several points of high symmetry of the Brillouin zone for different choices of potential. On the basis of these results the properties of the Fermi surface in the neighborhood of these points are ...

Temperature dependence of the band structure

physica status solidi (b), 1968
AbstractThe temperature dependent part of the self‐energy of an electron interacting with acoustic phonons is computed. At low temperatures the shifts of critical points are quadratic in temperature. Points of the type M0 and M1 shift to lower energies whereas the points M2 and M3 shift to higher energies.
