Esse modelo se baseia em um Hamiltoniano de Born, resolvido na aproximação da rede de Bethe. A partir da densidade local de modos normais de vibração, obtida pelo método das funções de Green, analisamos o espectro de absorção no infravermelho desse material / Abstract: We introduce a model for the lattice dynamics of a-Si1-xNx. This model is based on a Born Hamiltonian, solved in the Bethe lattice approximation. Starting from the local density of vibrational states, we analyze the infrared absorption spectra of this material / Mestrado / Física / Mestre em Física
