Remarks on the Spectral Properties of Tight Binding and Kronig-penney Models with Substitution Sequences #
نویسندگان
چکیده
We comment on some recent investigations on the electronic properties of models associated to the Thue-Morse chain and point out that their conclusions are in contradiction with rigorously proven theorems and indicate some of the sources of these misinterpretations. We brieey review and explain the current status of mathematical results in this eld and discuss some conjectures and open problems.

متن کاملEffect of Curvature on the Mechanical Properties of Graphene: A Density Functional Tight-binding Approach
Due to the high cost of experimental analyses, researchers used atomistic modeling methods for predicting the mechanical behavior of the materials in the fields of nanotechnology. In the pre-sent study the Self-Consistent Charge Density Functional Tight-Binding (SCC-DFTB) was used to calculate Young's moduli and average potential energy of the straight and curved graphenes with different curvat...
متن کامل1 N ov 1 99 6 Transport properties of one - dimensional Kronig - Penney models with correlated disorder
Transport properties of one-dimensional Kronig-Penney models with binary correlated disorder are analyzed using an approach based on classical Hamiltonian maps. In this method, extended states correspond to bound trajectories in the phase space of a parametrically excited linear oscillator, while the on site-potential of the original model is transformed to an external force. We show that in th...
متن کاملSome Remarks on Generalized Sequence Space of Bounded Variation of Sequences of Fuzzy Numbers
The idea of difference sequences of real (or complex) numbers was introducedby Ki zmaz cite{Kizmaz}. In this paper, using the difference operator and alacunary sequence, we introduce and examine the class of sequence $bv_{theta}left( Delta,mathcal{F}right) .$ We study some of its properties likesolidity, symmetricity, etc.
متن کاملOptical properties of silicon nano layers by using Kramers- Kronig method
Silicon thin layers are deposited on glass substrates with the thickness of 103 nm, 147 nm and 197 nm. The layers are produced with electron gun evaporation method under ultra-high vacuum condition. The optical Reectance and the Transmittance of produced layers were measured by using spectrophotometer. The optical functions such as, real and imaginary part of refractive index, real and imaginar...
