Query: Thermal conductivity of molybdenum disulfide nanotube from molecular
  dynamics simulations   Single layer molybdenum disulfide (SLMoS2), a semiconductor possesses
intrinsic bandgap and high electron mobility, has attracted great attention due
to its unique electronic, optical, mechanical and thermal properties. Although
thermal conductivity of SLMoS2 has been widely investigated recently, less
studies focus on molybdenum disulfide nanotube (MoS2NT). Here, the
comprehensive temperature, size and strain effect on thermal conductivity of
MoS2NT are investigated. A chirality-dependent strain effect is identified in
thermal conductivity of zigzag nanotube, in which the phonon group velocity can
be significantly reduced by strain. Besides, results show that thermal
conductivity has a ~T-1 and a ~L\b{eta} relation with temperature from 200 to
400 K and length from 10 to 320 nm, respectively. This work not only provides
feasible strategies to modulate the thermal conductivity of MoS2NT, but also
offers useful insights into the fundamental mechanisms that govern the thermal
conductivity, which can be used for the thermal management of low dimensional
materials in optical, electronic and thermoelectrical devices. Introduction.
