Band gap engineering in simultaneous phononic and photonic crystal slabs [PDF]

, 2010
We discuss the simultaneous existence of phononic and photonic band gaps in two types of phononic crystals slabs, namely periodic arrays of nanoholes in a Si membrane and of Si nanodots on a SiO2 membrane. In the former geometry, we investigate in detail

Band Structure of Topological Insulator BiSbTe1.25Se1.75

Scientific Reports, 2017
We present our angle resolved photoelectron spectroscopy (ARPES) and density functional theory results on quaternary topological insulator (TI) BiSbTe1.25Se1.75 (BSTS) confirming the non-trivial topology of the surface state bands (SSBs) in this compound.

Characterization of Pure and Pb2+ ion Doped Methylcellulose Based Biopolymer Electrolyte Films: Optical and Electrical Properties

International Journal of Electrochemical Science, 2018
Pb2+ ion-conducting biopolymer electrolyte films, based on methylcellulose (MC) were prepared, using the solution cast technique. The effect of Pb2+ doping concentration on the optical and electrical properties of host MC are described in this manuscript.

Collective states in 230Th: band structure [PDF]

Ядерна фізика та енергетика, 2009
Experimental data for the excited states in the deformed nucleus 230Th studied in the (p, t) reaction are analyzed. Sequences of the states are selected which can be treated as rotational bands and as multiplets of excitations.

Perpendicular magnetocrystalline anisotropy energy (MAE) of 111-surface slab of Fe2CoAl

Materials Research Express, 2020
We have analyzed the surface stability of different orientations(111, 001, 011) of Fe _2 CoAl (FCA) slabs. Among all the slabs, the orientation with 111-surface is found to be most stable with minimum energy.

Extrema positions of charge carrier band spectrum in thin bismuth films

Physics of Complex Systems, 2022
Many studies report an increase in charge carrier concentration in thin bismuth films as their thickness decreases at low temperatures. These results are obtained on the basis of data on resistivity, magnetoresistance, Hall coefficient, and thermal EMF ...
