WebOct 10, 2024 · In this work, the phononic surface spectrums were simulated by the following steps: 1) by calculating the phonon dispersion of a slab system; 2) First, we used the phonopyTB tool, installed in the root folder of WannierTools [ 47 ], to generate the phononic tight-binding Hamiltonian with the FORCE−CONSTANTS. WebA novel efficient method to calculate the scattering matrix (SM) of arbitrary tight-binding Hamiltonians is proposed, including cases with multiterminal structures.
