Readout of relaxation rates by nonadiabatic pumping spectroscopy
Roman-Pascal Riwar, Benoît Roche, Xavier Jehl +1
We put forward nonadiabatic charge pumping as a method for accessing the different charge relaxation rates as well as the relaxation rates of excited orbital states in double-quant…
Intrinsic and extrinsic decay of edge magnetoplasmons in graphene
N. Kumada, P. Roulleau, B. Roche +4
We investigate intrinsic and extrinsic decay of edge magnetoplasmons (EMPs) in graphene quantum Hall (QH) systems by high-frequency electronic measurements. From EMP resonances in…
A hybrid metal/semiconductor electron pump for quantum metrology
X. Jehl, B. Voisin, T. Charron +8
Electron pumps capable of delivering a current higher than 100pA with sufficient accuracy are likely to become the direct mise en pratique of the possible new quantum definition of…
A two-atom electron pump
B. Roche, R. -P. Riwar, B. Voisin +6
The fabrication of single atom transistors paved the way for electronics based on single dopants. Recently the spectrum of a single dopant was measured electrically by coupling two…
Detection of a large valley-orbit splitting in silicon with two-donor spectroscopy
Benoit Roche, Eva Dupont-Ferrier, Benoit Voisin +6
We measure a large valley-orbit splitting for shallow isolated phosphorus donors in a silicon gated nanowire. This splitting is close to the bulk value and well above previous repo…
Coupling and coherent electrical control of two dopants in a silicon nanowire
E. Dupont-Ferrier, B. Roche, B. Voisin +5
Electric control of individual atoms or molecules in a solid-state system offers a promising way to bring quantum mechanical functionalities into electronics. This idea has recentl…
