DOI: 10.1007/s10909-019-02292-6
Abstract: As it is known, the role of Coulomb correlations in hopping transport is still not understood in detail and different works contain controversial conclusions in this concern. In what follows, we are going to consider… read more here.

Abstract: Two-dimensional (2D) heterostructures often provide extraordinary carrier transport as exemplified by superconductivity or excitonic superfluidity. Recently, a double-layer graphene (Gr) separated by few-layered boron nitride demonstrated the Coulomb drag phenomenon: carriers in the active layer… read more here.

DOI: 10.1088/1367-2630/aa887e
Abstract: We report on Coulomb drag experiments between a bilayer graphene flake and a GaAs two-dimensional electron gas, where the charge-carrier densities of both systems can be tuned independently. For both p- and n-type graphene charge… read more here.

DOI: 10.1103/physrevlett.125.247701
Abstract: The Coulomb drag effect has been observed as a tiny current induced by both electron-hole asymmetry and interactions in normal coupled quantum dot devices. In the present work we show that the effect can be… read more here.
