Using the tight-binding approach, we calculate the thermoelectric properties of phosphorene nanorings in the absence and presence of a perpendicular magnetic field, and we investigate the effect of symmetrically and asymmetrically positioned leads. Our findings indicate that the symmetry/asymmetry of our designed nanostructures, the geometrical characteristics of the ring, and the magnetic flux are three ...

Методом теории функционала плотности рассчитаны зонная структура, плотности состояний и спектры рентгеновского поглощения K-края кислорода для перовскитных высокотемпературных сверхпроводников на основе BaBiO3 для разных уровней допирования калием в основном и оптически возбужденном состояниях. Показано, что в рамках данного подхода учет локальных структурных неоднородностей, обусловленных допированием и воздействием оптического излучения, позволяет корректно описать изменения свойств электронной подсистемы вблизи ...

The current paper demonstrates theoretical analysis of two types of spectral curves for several
configurations of system of two-level light emitters, considering the influence of local field and
close environment inside a transparent medium. Probe field absorption spectra and resonant
fluorescence spectra are calculated under excitation of a strong monochromatic cw laser. The
sensitivity of absorption and emission optical ...

Electron–phonon interaction strongly affects and often limits charge transport in organic semiconductors (OSs). However, approaches to its experimental probing are still in their infancy. In this study, we probe the local electron–phonon interaction (quantified by the charge-transfer reorganization energy) in small-molecule OSs by means of Raman spectroscopy. Applying density functional theory calculations to four series ...

We present low-temperature far-infrared study of Sm2BaNiO5. The lowest-frequency phonon of Sm2BaNiO5 generated by the motion of the Sm3+ ion demonstrates anomalous behaviour at temperatures lower than the Néel temperature, T<TN=55 K. This phonon hardens at the magnetic ordering although its frequency shift does not follow the magnetic order parameter. The observed phenomenon is responsible for ...

The phonon and electronic properties, the Eliashberg function and the temperature dependence of resistance of electride Ca2N are investigated by the DFT-LDA (density functional theory in local density approximation) plane-wave method. The phonon dispersion, the partial phonon density of states and the atomic eigenvectors of zero-center phonons are studied. The electronic band dispersion and partial ...

Analysis of the contribution of electron scattering on phonons, longitudinal and flexural resistance in the nanotube in a longitudinal magnetic field has been carried out quantitatively. The dependence of the conductance of the nanostructure on the nanotube radius, surface electron density, temperature, and Aharonov–Bohm parameter in the case of an isotropic phonon spectrum and taking ...

We report on the voltage response of carbon nanotube devices to sub-terahertz (THz) radiation. The devices contain carbon nanotubes (CNTs), which are over their length partially suspended and partially Van der Waals bonded to a SiO2 substrate, causing a difference in thermal contact. We observe a DC voltage upon exposure to 140GHz radiation. Based on ...

A numerical study of the thermodynamic properties of a superconducting quantum cylinder in a longitudinal magnetic field is carried out. Closed-form expressions for the critical temperature, the free energy, the heat capacity jump, and the magnetization difference between the superconducting and normal phases as functions of the nanotube parameters are obtained in limit cases. ...

Получена квантовая формула, описывающая зависимость продольной диэлектрической проницаемости нанотрубки от ее характерных параметров и от напряженности магнитного поля. Выделена мнимая часть диэлектрической проницаемости, проанализированы случаи больцмановского и вырожденного электронного газа. Для вырожденного электронного газа получены асимптотики поглощения в коротковолновой и длинноволновой областях. Показано, что коэффициент поглощения электромагнитной волны испытывает осцилляции Ааронова–Бома. ...
