| We demonstrate the optically detected long-range (>100 µm) ambipolar transport of photogenerated electrons and holes at room temperature by surface acoustic waves (SAWs) in (In,Ga)As-based quantum well structures coupled to an optical microcavity. We also show the control of the propagation direction of the carriers by a switch composed of orthogonal SAWbeams, which can be used as a basic control gate for information processing based on ambipolar transport. | |||
