Pumping of Quantum Dots with Surface Acoustic Waves
physica status solidi (b), 2001Surface acoustic waves on a semiconductor quantum well structure are accompanied by strong lateral piezo-electric fields. Those fields can ionize photo-generated excitons and trap the fragments, electron-hole pairs, in the moving lateral potential wells to the wave.

Acoustic-phonon scattering in a rectangular quantum wire
Physical Review B, 1993The rates of electron scattering by acoustic phonons in a rectangular quantum wire embedded into another material are calculated in the framework of the Fermi golden rule. Both intrasubband and intersubband electron scattering by acoustic phonons are considered. It has been shown that due to uncertainty of momentum conservation in quasi-one-dimensional

Observation of 3D acoustic quantum Hall states
Science BulletinQuantum Hall effect, the quantized transport phenomenon of electrons under strong magnetic fields, remains one of the hottest research topics in condensed matter physics since its discovery in 2D electronic systems. Recently, as a great advance in the research of quantum Hall effects, the quantum Hall effect in 3D systems, despite its big challenge ...

Biomedical Acoustics: Making a quantum leap in medicine
The Journal of the Acoustical Society of America, 2011At the dawn of a new era in medicine, the future of biomedical acoustics is bright. In the last century, we witnessed the introduction of ultrasound contrast agents, lithotripsy, and the visualization of ultrasound images in three dimensions. Currently, scientists are developing acoustic-based techniques for opening the blood–brain barrier transiently ...

Bulk Acoustic Quantum Transduction
Quantum networks of superconducting circuit quantum processors are an exciting prospect but are unfeasible without an efficient quantum interface between optical light and superconducting qubits. This problem motivates the development of a quantum microwave-to-optical transducer, a device that can faithfully transfer the state of a superconducting ...openaire +1 more source
