| Description | Journal: Nanotechnology The effect of biaxial tensile strain on the thermal transport properties of $MoS_{2}$ is investigated by combining first-principles calculations and the Boltzmann transport equation. The thermal conductivities of single layer $MoS_{2}$ are found to be heavily suppressed by the applied strains; even a moderate biaxial tensile strain, 2 ~ 4%, could result in a 10 ~ 20% reduction in the thermal conductivity. Most interestingly, the reduction rate of thermal conductivity is size-dependent, which is due to different dominant phonon scattering mechanisms at different sizes of $MoS_{2}$ samples. The sensitive strain dependence of thermal conductivity indicates that strain engineering could be an effective method to enhance the figure of merit for thermoelectric applications of $MoS_{2}$. |
