This work describes a ground breaking experiment, involving high sample quality and tunable geometry and very low temperatures where quantum effects are important. Electrons are confined to a two dimensional semiconductor interface and further restricted using electric fields. An integrable square cavity is modified by a tunable circular obstacle at the centre, leading to a chaotic Sinai billiard geometry. The system is open as there are two leads for measuring the conductance (inverse resistance) as a function of applied magnetic field. Fractal conductance fluctuations are selfsimilar structures in the conductance plotted as a function of field, and were only observed in the chaotic geometry. Experimentally relevant work on photon rather than electron billiards is that of Microresonators.
