Abstract
A silicon-related local vibrational mode absorption in AlGaAs is repor ted for the rust time. It consists of six peaks grouped around 450 cm( -1) which form a distinct pattern. We believe that the new local vibra tional mode absorption is a fingerprint of a single defect. Among the discussed microscopic structures the most plausible is a Si-Ga-Si-As p air complex with Si-As acceptor interacting with different Ga, Al near est neighbour local environments.
