| The patterns for the time integrated drag current induced by a pulsed beam of bulk phonons in a 2D gas of charge carriers are calculated. A beam of Planckian phonons propagates in a GaAs crystal. We considered a 2D gas of electrons lying in a {001} plane and a 2D gas of holes lying in the {311} plane. Planckian phonons are radiated by an extended (Gaussian) source. |
