In this study, the lattice dynamics of twisted graphene nanoribbons were investigated using the density-functional tight-binding method based on screw symmetry. The results showed that the reduction in phonon group velocity caused by twisting decreases the lattice thermal conductivity. These findings offer inspiration for designing graphene-based phononic devices tailored by inhomogeneous strain.
