We have measured a graphene double quantum dot device with multiple electrostatic gates that
are used to enhance control to investigate it. At low temperatures the transport measurements
reveal hone...
We calculate the mesoscopic admittance G(!) of a double quantum dot, which can be measured
directly using microwave techniques. This quantity shows a rich behavior. In particular, it is directly sens...
Double quantum dot with tunable coupling in an enhancement-mode silicon metal-oxide semiconductor device with lateral geometry
Double quantum dot enhancement-mode silicon lateral geometry
2010/11/17
We present transport measurements of a tunable silicon metal-oxide-semiconductor double quantum dot device with lateral geometry. Experimentally extracted gate-to-dot capacitances show that the device...
Detection of spin injection into a double quantum dot: Violation of magnetic-field-inversion symmetry of nuclear polarization instabilities
Detection of spin injection double quantum dot: Violation nuclear polarization instabilities
2010/11/19
In mesoscopic systems with spin-orbit coupling, spin-injection into quantum dots at zero magnetic eld is expected under a wide range of conditions. However, up to now, a viable approach for experimen...

Cotunneling effects GaAs vertical double quantum dot
2010/11/24
Semiconductor quantum dots have been a subject of intensive investigation over last two
decades. One reason is the proposal [1] to use spin state of electron in a quantum dot as a
quantum bit of inf...
Two-spin dephasing by electron-phonon interaction in semiconductor double quantum dots
Two-spin dephasing electron-phonon interaction semiconductor double quantum dots
2010/11/11
We study electron-phonon interaction induced decoherence between two-electron singlet and triplet states in a semiconductor double quantum dot using a spin-boson model. We investigate the onset and ti...
