Popis:	We study the spatio-temporal dynamics of the oscillatory photo-electrodissolution of n-type Si in a fluoride-containing electrolyte under anodic potentials using in-situ ellipsometric imaging. When lowering the illumination intensity step-wise, we successively observe uniform oscillations, modulated amplitude clusters, and the coexistence of multi-frequency clusters i.e., regions with different frequencies, with a stationary domain. We argue that the multi-frequency clusters emerge due to an adaptive, nonlinear, and nonlocal coupling, similar to those found in the context of neural dynamics. Comment: 7 pages, 4 figures, v2 with corrected reference formatting
