61.72.-y - Opis:
- Localised vibrational mode infrared absorption (10 K) and Hall measurements were made on a series of Si doped Al$\text{}_{x}$Ga$\text{}_{1-x}$As samples with 0 ≤ x ≤ 0.25 grown by liquid phase epitaxy. Localised vibrational modes were detected from Si$\text{}_{Ga}$ donors, Si$\text{}_{As}$ acceptors and Si$\text{}_{Ga}$-Si$\text{}_{As}$ pairs which increased in frequency as x increased. The assignments of new lines observed at 386, 388 and 391 cm$\text{}^{-1}$ are discussed in relation to possible perturbations of the lines from Si$\text{}_{Ga}$ or Si$\text{}_{As}$. The presence of DX centres was inferred from observed persistent photoconductivity and attempts were made to relate this result to the presence of the new IR lines.
