TL;DR: In this paper, the authors studied the electronic transport properties of twisted bilayer bilayer graphene and showed the formation of van Hove singularities that are highly tunable by changing either the twist angle or external electric field and can cause strong correlation effects under optimum conditions.

TL;DR: Control the interactions by proximity screening with gate dielectrics of nanometer thickness, revealing qualitative changes in concentration and temperature dependences, and validating their analysis using electron hydrodynamics and umklapp scattering approaches.

TL;DR: In this paper, the authors studied the electronic transport properties in twisted trilayer graphene (tTLG, bilayer on top of monolayer graphene heterostructure) and observed the formation of van Hove singularities which are highly tunable by twist angle and displacement field and can cause strong correlation effects under optimum conditions.

TL;DR: In this article, the electron-electron scattering length in graphene was measured using gate dielectric thicknesses of a few nm, much smaller than a typical separation between electrons.

TL;DR: It is shown that, in graphene-on-boron-nitride superlattices, Brown-Zak fermions can exhibit mobilities above 106 cm2 V−1 s−1 and the mean free path exceeding several micrometers and all the degeneracies (spin, valley and mini-valley) can be lifted by exchange interactions below 1 K.
