In this thesis the oscillatory electrodissolution of silicon is investigated. We systematically
study and classify the different types of oscillations and identify high amplitude oscillations
in the voltage drop across the electrode as a unified class of oscillations present under po-
tentiostatic, galvanostatic and mixed control. Under appropriate coupling these oscillations
then exhibit a rich variety of patterns forming spontaneously in the oxide layer covering the
electrode including such complex patterns as ’chimera states’, i.e. the coexistence of synchro-
nized and desynchronized regions. We investigate these patterns in detail and, by means of
comparing them to theoretical simulations obtained with a generic ansatz, identify them as
genuine dynamical phenomena.
