Tensile strain enhances four-phonon scattering and suppresses thermal conductivity in monolayer MoSe.
Mechanical strain provides an effective means of tuning thermal conductivity in two-dimensional (2D) materials, but its effect on higher-order phonon scattering in fractional-layer materials remains unclear. Here, we investigate the tensile strain-dependent thermal conductivity of fractional-layer MoSe2, structurally c...
