The band structure of polyferrocenylene
Physics Letters A, 1983The 1D polyferrocenylene system is employed for an analysis of “hybridization” effects in the HF bands of complex organometal1ic solids. An important physical consequence of this type of hybridization is a strong k-dependence in the character of the CO microstates (i.e. correlation between localized metal-centered and delocalized ligand basis functions)

Experimental band structure of lead
Physical Review B, 1990By using angle-resolved photoemission with synchrotron radiation, we have determined accurate energy-versus-momentum dispersion relations along symmetry lines \ensuremath{\Gamma}X and \ensuremath{\Gamma}KX for lead crystals. These directions are mapped out by recording normal-emission photoelectron spectra at low temperatures (20 K) from Pb(100) and Pb(

Experimental Band Structure of Na
Physical Review Letters, 1985Normal-emission angle-resolved photoemission data from Na(110) are presented. Two discrepancies between these data and the predictions of free-electron theory are observed. First, the occupied-band width is 2.5 eV, while theory predicts 3.2 eV. Second, the bands near the Fermi level appear to have been severely distorted, as could be produced by a ...

Physical Review, 1961
The orthogonalized plane wave method, in a perturbation approximation, is used to compute the lowest lying conduction states in (fcc) solid argon at the symmetry points GAMMA , X, L, and K. The 3s and 3p valence bands are treated by tight-binding theory.

Quasiparticle Band Structure of CdS
Physical Review Letters, 1995Quasiparticle band structure calculations which include the most important cationic core states in the $\mathrm{GW}$ approximation of the self-energy operator are reported for a prototype II-VI semiconductor. The most salient feature of our results for cubic CdS is the finding that the complete cationic $N$ shell needs to be included in the ...

The topology of electronic band structures
Nature Materials, 2020The study of topology as it relates to physical systems has rapidly accelerated during the past decade. Critical to the realization of new topological phases is an understanding of the materials that exhibit them and precise control of the materials chemistry.

Band structure of semiconductor alloys
Physical Review B, 1988The band structures of several semiconductor alloys have been calculated by a method which takes into account the reduced local symmetry in the alloys. The alloy band structure is found from the weighted average of the band structures calculated for crystals formed from the different nearest-neighbor configurations that can occur in the alloys. In this

Banded structure of drifting macroalgae
Marine Pollution Bulletin, 2009A massive bloom of macroalgae occurred in the western Yellow Sea at the end of May, 2008, and lasted for nearly 2 months. The surface-drifting macroalgae was observed to accumulate in a pattern dominated by linear bands. The maximum length of individual algal bands exceeded 10 km and the distance between neighboring bands ranged from hundreds of meters

Energy Band Structure of Copper
Physical Review, 1963The $E(k)$ values were computed for the equivalent of 2048 points in the Brillouin zone and for energies ranging from the bottom of the $4s$-band to approximately 2 Ry above the Fermi energy. From these calculations the Fermi energy, Fermi surface, and density of states were determined.
