We present a model for the self-similar magneto-conductance recently observed in the low-temperature measurement of a semiconductor Sinai billiard. To model the self-similar behaviour, we investigate the scaling properties observed over more than three orders of magnitude in magnetic field. The magneto-conductance is found to be composed of a summation of damped cosines scaled according to a Weierstrass function —a known generator of self-similar behaviour. Our preliminary model, based on a single hierarchy of oscillations with magnetic flux periods of h/2e, provides a close match to the experimental data. However, a refined model featuring co-existing h/e and h/2e hierarchies matches the features of the data with remarkable accuracy.
