Large tunable valley splitting in edge-free graphene quantum dots on boron nitride
Nils M. Freitag, Tobias Reisch, Larisa A. Chizhova +10
Coherent manipulation of binary degrees of freedom is at the heart of modern quantum technologies. Graphene offers two binary degrees: the electron spin and the valley. Efficient s…
Observing imperfection in atomic interfaces for van der Waals heterostructures
Aidan. P. Rooney, Aleksey Kozikov, Alexander N. Rudenko +8
Vertically stacked van der Waals heterostructures are a lucrative platform for exploring the rich electronic and optoelectronic phenomena in two-dimensional materials. Their perfor…
Unraveling the 3D atomic structure of a suspended graphene/hBN van der Waals heterostructure
G. Argentero, A. Mittelberger, M. R. A. Monazam +7
In this work we demonstrate that a free-standing van der Waals heterostructure, usually regarded as a flat object, can exhibit an intrinsic buckled atomic structure resulting from…
