Two vibrational absorption lines at 3015.5 and 3092.8 cm Γ€1 , observed in liquid encapsulation Czochralski-grown GaAs, are investigated and are assigned to hydrogen stretching modes. The intensities of both lines measured in different samples are strictly correlated. Samples containing both hydrogen

Infrared absorption on GaAs doped with Chalcogenides under hydrogen plasma treatment has shown the presence of two new localised modes, namely stretching and wagging modes. We present a simple nine atom molecular model to compute these defect modes by assuming the hydrogen to be bound in the antibon
