Temperature shift of intraband absorption peak in tunnel-coupled QW structure
An experimental study of the intersubband light absorption by the 100-period GaAs/Al0.25Ga0.75As double quantum well heterostructure doped with silicon is reported and interpreted. Small temperature redshift of the 1–3 ...
Effects of external electric field on the optical and electronic properties of blue phosphorene nanoribbons: A DFT study
Using first principles calculations we investigate the effect of external electric fields in the optical and electronic properties of blue-phosphorene nanoribbons. It is shown that the application of a static external ...
Effects of hydrostatic pressure and electric field on the electron-related optical properties in GaAs multiple quantum well
The properties of the electronic structure of a finite-barrier semiconductor multiple quantum well are investigated taking into account the effects of the application of a static electric field and hydrostatic pressure. ...
Background impurities in Si0.8 Ge0.2/Si/Si0.8 Ge0.2 n-type δ-doped QW
Additional (residual) impurities in the barriers change the energy profile of a quantum well. This means that they alter the ionization energy for the impurity delta layer situated within the quantum well. In turn, this ...
Analysis of light propagation in quasiregular and hybrid Rudin–Shapiro one-dimensional photonic crystals with superconducting layers
The transmittance spectrum of a one-dimensional hybrid photonic crystal built from the suitable arrangement of periodic and quasiregular Rudin–Shapiro heterolayers that include superconducting slabs is investigated. The ...
Narrowband Filters Designed from Hybrid One-Dimensional Periodic/Quasiperiodic Photonic Crystals with a Single Defect Layer
We report the transmission spectra and electric field amplitudes of electromagnetic modes propagating in hybrid periodic/quasiperiodic multilayer photonic structures in one dimension (1D). We consider the case of the ...
