Abstract

We assume that Al x Ga 1-x As layers may be classified into two general groups of different configurations: one consisting of mesoscopic-size clusters differing in their cation content, but otherwise fairly homogeneous (I), while in the other the cation concentration fluctuates statistically on a microscopic scale about a well-defined average (II). In this way we explain the distinct behavior of these two classes of samples. In group I, phonon lines are broad but reasonably symmetric, room-temperature luminescence is present and a second-order resonant Raman spectrum is observed. In group II, phonon lines are narrow but asymmetric, no luminescence and no second-order Raman could be detected
