The scaling structure of attractors at the transition from quasiperiodicity to chaos is studied for an electron-hole plasma instability in a Ge crystal. The scaling function f(..cap alpha..) spectrum calculated from the time series of the plasma current oscillation at the onset of chaos is in good agreement with that of a circle-map model. The experimental power spectrum also confirms that the transition to chaos is well described by the circle map. The extrinsic noise effect on the f(..cap alpha..) spectrum is discussed by using the circle map.
