Self-consistent treatment of v-groove quantum wire band structure in no parabolic approximation [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2004
The self-consistent no parabolic calculation of a V-groove-quantum-wire (VQWR) band structure is presented. A comparison with the parabolic flat-band model of VQWR shows that both, the self-consistency and the nonparabolicity shift sub band edges, in ...

Effect of Hydrostatic Pressure on the Electronic Structure of the Crystal NiMnAs [PDF]

open access: yesЖурнал нано- та електронної фізики, 2017
The electronic energy spectra and densities of the electronic states of semimetallic NiMnAs crystals are calculated without taking into account the pressure and strong electron correlations and with the inclusion of the latter in the calculation scheme ...

Calculation of Sea Radiance in Infrared Band

open access: yes2006 IEEE 14th Signal Processing and Communications Applications, 2006
The sea surface statistical models are directly related with the calculation of the total radiance reflected from the sea surface seen by the observer. Three major work which model the sea surface slope statistics are Cox and Munk, Mermelstein and Shaw-Churnside models.

Application of Fibonacci heap to fast marching method

open access: yesOpen Physics, 2021
The fast marching method (FMM) is an efficient, stable and adaptable travel time calculation method. In the realization of this method, it is necessary to select the minimum travel time node from the narrow band many times.

Order Projection in OAr(E,F)

open access: yesСовременная математика: Фундаментальные направления, 2022
We investigate order projections onto different bands in the space of all regular orthogonally additive operators. In particular, we obtain formulas for calculation of the order projections onto the band generated by a directed set of positive ...

Ab-initio calculation of band alignments for opto-electronic simulations

open access: yesAIP Advances, 2019
A modified core-to-valence band maximum approach is applied to calculate band offsets of strained III/V semiconductor hetero junctions. The method is used for the analysis of (In,Ga)As/GaAs/Ga(As,Sb) multi-quantum well structures.
