We have studied the onset of dissipation in the quantum Hall effect (QHE) in different antidot arrays (periodic or aperiodic antidot arrays, and single lines of antidots), patterned on a two-dimensional electron system. In periodic arrays, the breakdown current is systematically reduced with increasing antidot density. In comparable aperiodic arrays, the breakdown current is markedly lower, and the electron temperature starts rising at lower currents than in periodic arrays. Single lines of antidots across the current channel cause only a small reduction of the breakdown current, indicating the relevance of avalanche electron heating. In arrays of very small antidots, a suppression of the electron heating due to additional scattering and a complete absence of hot-electron-induced hysteresis in the current-voltage characteristics were observed.
