Self-induced acoustic transparency in semiconductor quantum films - art. no. 226803

We develop a quantum theory of the nonlinear interaction between intense su rface acoustic waves and electrons in a quantum well in the regime of movin g quantum wires and dots. In the quantum nonlinear regime, the sound attenu ation exhibits quantum oscillations and dramatically decreases with increas ing quantization. In the case of dynamically created electron dots formed b y two acoustic waves, the waves can propagate without any dissipation in th e limit of high sound intensity and, hence, the electron quantum film acts as an acoustically quasitransparent material.
