Vibrational properties of amorphous semiconductors

Description

A model for the lattice dynamics of a-Si1-X NX is introduced. This model is based on a Born hamiltonian, solved in the Bethe lattice approximation. Starting from the local density of vibrational states, we analize the infrared absoption spectra of this material. (author)

Abstract (Portuguese)

Apresenta-se um modelo para a dinamica de rede do a-Si1-X NX. Esse modelo se baseia em um hamiltoniano de Born, resolvido na aproximacao da rede de Bethe. A partir da densidade local de modos normais de vibracao, obtida pelo metodo das funcoes de Green, analisamos o espectro de absorcaono infravermelho desse material. (autor)
