Your first band diagram

Getting Started

Frequencies are returned in dimensionless units of c/ac/a, where aa is the lattice constant. The k-path is picked automatically from the lattice preset (Gamma,X,M,GammaGamma, X, M, Gamma for a square), and the returned freqs array always has shape (nk,nbands)(n_k, n_\text{bands}), sorted ascending in frequency at every k-point.
