Electric-field-induced modulation of thermal conductivity in poly(vinylidene fluoride)

Two-dimensional layered MSi2N4 (M = Mo, W) as promising thermal management materials: a comparative study

“…The thermal conductivity of 2D semiconductors is one of their significant phononic properties that has attracted considerable interest, [7][8][9][10][11] which involves their layered structural features of out-of-plane van der Waals bonds and in-plane covalent bonds. Due to the atomically thin monolayer with van der Waals bonds along the out-of-plane direction, the thermal conductivities of 2D semiconductors are generally thickness-dependent in both out-of-plane, and in-plane directions.…”

Efficient mechanical modulation of the phonon thermal conductivity of Mo6S6 nanowires

“…To reveal the effect of strain on the phonon properties in detail, the spectral energy density (SED) of the Mo 6 S 6 NW is computed under different strains, which has been widely used to understand the thermal properties of low-dimensional materials. [69][70][71] Fig. 3a shows the SED spectrum (ω < ω A max ) of the Mo 6 S 6 NWs at critical axial tension strains of 0, 0.015 and 0.04, while the full-frequency SED spectrum is shown in Fig.…”

Impact of Atomic Coating on Thermal Conductivity of Nano Materials

“…Although the present review clearly shows the significant impact of atomic coating on the thermal conductivity of nano materials, further systematic investigations are still needed, from both experimental and theoretical efforts. It is worth emphasizing that a wide range of mechanism may be responsible for the change in thermal conductivity, including phonon hydrodynamic transport [105], back scattering [106], quantum confinement effect [107], size dependence [108,109], superstructure [110,111], external field [112], strain [113,114] with each of them may be dominant in different range of parameters. Because single study may only focus on one mechanism, the dominant role of each mechanism in different range still deserves further systematic study.…”
