We report a quantitative study of ballistic transport, via measurements of commensurability oscillations (CO’s), in a two-dimensional electron system confined to a wide square quantum well with two electric subbands occupied. The Fourier power spectrum of the CO’s shows two clear-frequency components that correspond to ballistic transport in the upper and lower subbands. Through inverse Fourier transformation of each individual frequency component, we reconstruct the CO’s of ballistic electrons in different subbands and extract their scattering times.
