Strain-controlled phonon transport in van der Waals hetero-structures: a quantum study
We investigate phonon transport in strained van der Waals heterostructures using a first-principles nonequilibrium Green’s function (NEGF) approach. For monolayer MoS 2 , biaxial and uniaxial in-plane strains strongly modify phonon dispersion and transmission. Compressive strain stiffens the lattice and enhances...
