Electron Spin Excited States Spectroscopy in a Quantum Dot Probed by QPC Back-action
HaiOu Li, Ming Xiao, Gang Cao +6
The quantum point contact (QPC) back-action has been found to cause non-thermal-equilibrium excitations to the electron spin states in a quantum dot (QD). Here we use back-action a…
Back-action Driven Electron Spin Singlet-Triplet Excitation in a GaAs Quantum Dot
Gang Cao, Ming Xiao, HaiOu Li +6
In a single quantum dot (QD), the electrons were driven out of thermal equilibrium by the back-action from a nearby quantum point contact (QPC). We found the driving to energy exci…
Back-action Induced Non-equilibrium Effect in Electron Charge Counting Statistics
HaiOu Li, Ming Xiao, Gang Cao +6
We report our study of the real-time charge counting statistics measured by a quantum point contact (QPC) coupled to a single quantum dot (QD) under different back-action strength.…
Gates controlled parallel-coupled double quantum dot on both single layer and bilayer graphene
Lin-Jun Wang, Guo-Ping Guo, Da Wei +5
Here we report the fabrication and quantum transport measurements of gates controlled parallel-coupled double quantum dot on both bilayer and single layer graphene. It is shown tha…
