Orientation and size effects on phonon thermal conductivity in silicon/germanium multilayer structures Open

Alexander L. Khamets, Ivan I. Khaliava, I. V. Safronov, А. Б. Филонов, Д. Б. Мигас · 2023

We study the effect of morphology on the in- and cross-plane phonon thermal conductivity of the (001), (110), and (111) oriented Si/Ge multilayer films by means of non-equilibrium molecular dynamics at 300 K. The extended comparison of the…

Effect of surface morphology and interfaces on longitudinal phonon thermal conductivity in Ge(001) and Si/Ge(001) thin-film structures Open

A. L. Khamets, I. V. Safronov, А. Б. Филонов, Д. Б. Мигас · 2023

In this work the method of non-equilibrium molecular dynamics was used to study the longitudinal phonon thermal transport at 300 K in nanoscale homogenous Ge(001) and layered Si/Ge(001) thin films with p(2x1) surface reconstruction along d…

Effect of morphology on the phonon thermal conductivity in Si/Ge superlattice nanowires Open

Ivan I. Khaliava, Alexander L. Khamets, I. V. Safronov, А. Б. Филонов, Takashi Suemasu , et al. · 2022

We used nonequilibrium molecular dynamics to investigate the role of morphology in the phonon thermal conductivity of 〈100〉, 〈110〉, 〈111〉 and 〈112〉-oriented Si/Ge superlattice nanowires at 300 K. Such nanowires with 〈112〉 growth direction …

Effect of morphology on the phonon thermal conductivity of Si, Ge, and Si/Ge core/shell nanowires Open

Khaliava I. I, A. L. Khamets, I. V. Safronov, Filonov A.B., Migas D.B. · 2022

An additional factor in reducing thermal conductivity for thermoelectric applications of semiconductor nanowires is a change in morphology. In this paper, for Si, Ge and core/shell Si/Ge nanowires the effect of the volume fraction and the …

Effect of surface and interfaces on longitudinal thermal transport in thin-film Si/Ge structures Open

A. L. Khamets, I. I. Khaliava, I. V. Safronov, А. Б. Филонов, Д. Б. Мигас · 2022

One of the main approaches to increase the thermoelectric figure of merit of materials is to reduce their thermal conductivity and, in this respect, the surface and possible interfaces play an important role in low-dimensional structures. …
