Abstract
A quantum dot is created within a suspended nanobridge containing a two-dimensional electron gas. The electron current through this dot exhibits well-pronounced Coulomb blockade oscillations. When surface acoustic waves (SAW) are driven through the nanobridge, Coulomb blockade peaks are shifted. To explain this feature, we derive the expressions for the quantum dot level populations and electron currents through these levels and show that SAW-induced Rabi oscillations lead to the observed phenomenology.
Highlights
As modern electronic devices become smaller, it is compulsory to investigate possible quantum effects, which emerge due to the electron confinement [1]
We derive the expressions for the quantum dot level populations and electron currents through these levels and show that surface acoustic waves (SAW)-induced Rabi oscillations lead to the observed phenomenology
As typical SAW amplitudes can be in the range of nanometers, they effectively modulate the acoustic properties of nanomechanical devices
