Abstract
The observed fine structure of the localized vibrational modes of an isolated carbon impurity in GaAs is examined with use of a real-space approach based on the recursion method. The origins of the individual modes are identified and changes in the local force constants are discussed in terms of fitting the theoretical results to the experimental values.Keywords
