Abstract Scope |
We implement a method for calculating the local density of states (LDoS) for an incommensurate tri-layer 1D chain. This algorithm, introduced in the literature, employs an equidistribution theorem to parameterize and predict the distribution of local geometries, thus overcoming the limitations of approximating incommensurate geometries via large supercells and introducing artificial strain to the system. We report preliminary numerical observation of band-like features, indicative of long-range scattering behavior in momentum space. |
