Abstract

The objective of this paper is to discuss the relationship between the vibrational properties of an amorphous solid and the local atomic structure. Vibrational spectroscopy is an indirect structural probe, inasmuch as it requires a theory or model to relate spectral features to specific types of local bonding arrangements. It is complementary to other probes of local atomic structure, such as x-ray or neutron scattering which give direct information about bond-lengths and other aspects of atomic-scale geometry. We shall concentrate here on two specific types of amorphous solids: oxide and chalcogenide glasses, and amorphous silicon (a-Si) based alloys. The vibrational spectra of these materials, and the methods used to obtain information about their atomic structure, will illustrate techniques of analysis which are applicable to other material systems as well.
