Kondo cloud conductance in cavity-coupled quantum dots with asymmetric barriers
D. Fossion, V. Champain, S. Mohapatra +9
The Kondo effect emerges when a localized spin is screened by conduction electrons, giving rise to a strongly-correlated many-body ground state. In this work, we investigate this p…
Quantifying the local mechanical properties of twisted double bilayer graphene
Alessandra Canetta, Sergio Gonzalez-Munoz, Viet-Hung Nguyen +13
Nanomechanical measurements of minimally twisted van der Waals materials remained elusive despite their fundamental importance for device realisation. Here, we use Ultrasonic Force…
Reconstructing the potential configuration in a high-mobility semiconductor heterostructure with scanning gate microscopy
Gaëtan J. Percebois, Antonio Lacerda-Santos, Boris Brun +3
The weak disorder potential seen by the electrons of a two-dimensional electron gas in high-mobility semiconductor heterostructures leads to fluctuations in the physical properties…
Spectroscopic assessment of short-term nitric acid doping of epitaxial graphene
Ngoc Thanh Mai Tran, Swapnil M. Mhatre, Cristiane N. Santos +10
This work reports information on the transience of hole doping in epitaxial graphene devices when nitric acid is used as an adsorbent. Under vacuum conditions, desorption processes…
Graphene whisperitronics: transducing whispering gallery modes into electronic transport
Boris Brun, Viet-Hung Nguyen, Nicolas Moreau +6
When confined in circular cavities, graphene relativistic charge carriers occupy whispering gallery modes (WGM) in analogy to classical acoustic and optical fields. The rich geomet…
Quantum Hall nano-interferometer in graphene
N. Moreau, B. Brun, S. Somanchi +4
Quantum Hall edge states offer avenues for quasiparticle interferometry, provided that the ratio between phase coherence length and quantum Hall interferometer (QHI) size is large…
