Extremely short optical pulse in a system of nanotubes with adsorbed hydrogen

“…Fig. 2 shows the pattern of electromagnetic wave propagation in an array of nanotubes with the use of both the original dispersion relation (2) and when using the model under study (5). We show the dependence of the field at different times.…”

“…Using the semiclassical approximation, let us find the current density that is present implicitly in Eq. (5). In this approximation, the evolution of an ensemble of Fermi particles is described by the classical Boltzmann kinetic equation in the model of relaxation times [21] …”

“…High mobility of electrons in carbon nanotubes and their unique electrical characteristics attract an attention to them, as to a possible alternative to the silicon base of the modern microelectronics [1][2][3][4]. Although usually the dispersion of electrons in carbon nanotubes is chosen from the imposition of periodic boundary conditions on the dispersion relation in graphene it should be noted that carbon nanotubes can easily adsorb various impurities and, as a result, a proper account of the interaction within electronic system of nanotubes becomes a difficult task [5,6]. In particular, the interaction of electrons of nanotubes and impurity electrons can lead to a qualitative change in the energy spectrum (for example, the formation of a gap in the spectrum), and therefore propagation of optical pulses becomes possible.…”

Concomitant coronary and multiple arch vessel stenoses in patients treated with external beam radiation: Pathophysiological basis and endovascular treatment

“…The current paper continues a series of our articles devoted to the study of carbon nanotube adsorption properties 36–42 and to find out the mechanism of chemisorption processes. The aim of our paper is to present the consecutive quantum‐chemical investigation results of hiral SWNT adsorption properties regarding the atomic hydrogenation and fluorination.…”
