Nanoscale Mach-Zehnder interferometer with spin-resolved quantum Hall edge states
Biswajit Karmakar, Davide Venturelli, Luca Chirolli +7
We realize a nanoscale-area Mach-Zehnder interferometer with co-propagating quantum Hall spin-resolved edge states and demonstrate the persistence of gate-controlled quantum interf…
Fabrication of Artificial Graphene in a GaAs Quantum Heterostructure
Diego Scarabelli, Sheng Wang, Yuliya Y. Kuznetsova +7
The unusual electronic properties of graphene, which are a direct consequence of its two-dimensional (2D) honeycomb lattice, have attracted a great deal of attention in recent year…
Electrical plasmon detection in graphene waveguides
Iacopo Torre, Andrea Tomadin, Roman Krahne +2
We present a simple device architecture that allows all-electrical detection of plasmons in a graphene waveguide. The key principle of our electrical plasmon detection scheme is th…
