Molecule States in a Gate Tunable Graphene Double Quantum Dot
Molecule States Gate Tunable Graphene Double Quantum Dot
2010/11/25
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...
Correlation- and Interference-Induced Suppression and Enhancement of Current in a two-level Quantum Dot
Correlation uppression Enhancement of Current

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...
