|Title:||Evidence For Photon Anti-bunching In Acoustically Pumped Dots|
|Author:||Couto Jr. O.D.D.|
|Abstract:||We demonstrate the controlled transfer of photoexcited carriers by a surface acoustic wave (SAW) between coupled quantum wells, wires, and dots grown on a semiconductor surface. The quantum wires and dots used in the experiments are embedded at photolithographically defined positions within an (Al,Ga)As/GaAs (311)A-oriented quantum well grown by molecular beam epitaxy. We give experimental evidence for the anti-bunching of photons emitted in a quantum dot pumped by electrons and holes transported from the quantum well by a surface acoustic wave. © 2009 Elsevier B.V.
