Optical and reduced band gap in n- and p-type GaN and AlN
(2002-09)
We present a full band calculation of the doping-induced energy shifts of the conduction-band minimum and the valence-band maximum for n- and p-type GaN and AlN. Both wurtzite and zinc-blende structures have been considered. ...
Electronic band-edge properties of rock
(2008)
The electronic band-edges of lead chalcogenides PbY and tin chalcogenides SnY (where Y = S, Se, and Te) are investigated by the means of a full-potential linearized augmented plane wave (FPLAPW) method and the local density ...
Time and band limiting for matrix valued functions, an example
(2015)
The main purpose of this paper is to extend to a situation involving matrix valued orthogonal polynomials and spherical functions, a result that traces its origin and its importance to work of Claude Shannon in laying the ...
Band sizes of southeastern Brazilian hummingbirds
(Associação Field Ornithologists, 1996-06-01)
Aluminum numbered bands have been used to mark Brazilian hummingbirds since 1993 to obtain biological data as well as ascertain movements and longevities. Bands should be made as narrow as possible by cutting close to the ...

Obtainment of the density of states in the band tails of hydrogenated amorphous silicon
(American Institute of Physics, 2017-08)
In this work, we present two new pairs of formulas to obtain a spectroscopy of the density of states (DOS) in each band tail of hydrogenated amorphous silicon (a-Si:H) from photoconductivity-based measurements. The formulas ...
Carrier Frequency Offset Compensation for OFDMA Systems Using Circular Banded Matrices
(Planta Piloto de Ingeniería Química, 2013-07)
Orthogonal frequency division multiple access (OFDMA) is a multiuser communication technique that allocates to each user a set of orthogonal carriers. In the presence of carrier frequency offset (CFO) the orthogonality ...
Influence of the surface band structure on electron emission spectra from metal surfaces
(American Physical Society, 2014-04)
Electron distributions produced by grazing impact of fast protons on Mg(0001), Cu(111), Ag(111), and Au(111) surfaces are investigated, focusing on the effects of the electronic band structure. The process is described ...
