Abstract
Optical probe studies of propagating acoustoelectric domains in n‐GaAs reveal a self‐narrowing of the domain during growth, and an apparent limitation to the peak acoustic density in the domain, illustrating the role of flux‐dependent processes in domain evolution. A mechanism is discussed, based on evidence for changes in spectral composition of the domain at high acoustic intensity.Keywords
