    • The influence of the transverse component of the SAW piezoelectric field on the transport properties will be neglected due to the strong restriction to the tranverse motion imposed by the quantum well confinement.

    • The product np has been taken in previous works as a measure of the excitonic recombination rate (see, for example, Refs. 9 and 15). As shown in Sec. II, this approach is not strictly correct. Nevertheless, this does not mean that the product np is completely irrelevant, since cnp gives the rate of generation of excitons at a given point, which subsequently decay radiatively. The exciton lifetime, however, may also be limited by the field-induced ionization.

    • PL(x,t). In order to simulate as closely as possible the experimental situation, (Refs. 9, 10, and 16) we have chosen to integrate in a symmetric interval around the spot position. Nevertheless, due to the asymmetry imposed on the system by the traveling SAW, part of the recombination takes place outside the spot and is, therefore, not taken into account in Fig. 5.
