Magic-angle bilayer graphene nano-calorimeters -- towards broadband, energy-resolving single photon detection
P. Seifert, X. Lu, P. Stepanov +5
Because of the ultra-low photon energies in the mid-infrared and terahertz frequencies, in these bands photodetectors are notoriously underdeveloped, and broadband single photon de…
Control of electron-electron interaction in graphene by proximity screening
M. Kim, S. G. Xu, A. I. Berdyugin +14
Electron-electron interactions play a critical role in many condensed matter phenomena, and it is tempting to find a way to control them by changing the interactions' strength. One…
Visualizing Poiseuille flow of hydrodynamic electrons
Joseph A. Sulpizio, Lior Ella, Asaf Rozen +12
Hydrodynamics is a general description for the flow of a fluid, and is expected to hold even for fundamental particles such as electrons when inter-particle interactions dominate.…
A Bipartite Kronig-Penney Model with Dirac Potential Scatterers
Thomas Benjamin Smith, Alessandro Principi
Here we present a simple extension to the age-old Kronig-Penney model, which is made to be bipartite by varying either the scatterer separations or the potential heights. In doing…
Breakdown of the Wiedemann-Franz law in AB-stacked bilayer graphene
Mohammad Zarenia, Giovanni Vignale, Thomas Benjamin Smith +1
We present a simple theory of thermoelectric transport in bilayer graphene and report our results for the electrical resistivity, the thermal resistivity, the Seebeck coefficient,…
