Observation of ballistic upstream modes at fractional quantum Hall edges of graphene
Ravi Kumar, Saurabh Kumar Srivastav, Christian Spånslätt +5
The structure of edge modes at the boundary of quantum Hall (QH) phases forms the basis for understanding low energy transport properties. In particular, the presence of ``upstream…
Enhanced electron-phonon coupling in doubly aligned hexagonal boron nitride bilayer graphene heterostructure
Manabendra Kuiri, Saurabh Kumar Srivastav, Sujay Ray +4
The relative twist angle in heterostructures of two-dimensional (2D) materials with similar lattice constants result in a dramatic alteration of the electronic properties. Here, we…
Hexagonal Boron Nitride-Graphene Heterostructures with Enhanced Interfacial Thermal Conductance for Thermal Management Applications
Saheb Karak, Suvodeep Paul, Devesh Negi +4
Atomically thin monolayers of graphene show excellent electronic properties which have led to a great deal of research on their use in nanoscale devices. However, heat management o…
Electric-field-tunable valley Zeeman effect in bilayer graphene heterostructures: Realization of the spin-orbit valve effect
Priya Tiwari, Saurabh Kumar Srivastav, Aveek Bid
We report the discovery of electric-field-induced transition from a topologically trivial to a topologically nontrivial band structure in an atomically sharp heterostructure of bil…
