Coulomb drag is a transport phenomenon whereby long-range Coulomb interaction
between charge carriers in two closely spaced but electrically isolated conductors induces a …

Coulomb drag is a frictional coupling between electric currents flowing in spatially separated
conducting layers. It is caused by interlayer electron–electron interactions. Previously, only …

This review is devoted to the theory of electron-hole superfluidity in bilayer systems. This is a
discussion of the state in which electrons and holes from adjacent layers form bound pairs …

If bosonic particles are cooled down below the temperature of quantum degeneracy, they
can spontaneously form a coherent state in which individual matter waves synchronize and …

Exciton bound states in solids between electrons and holes are predicted to form a
superfluid at high temperatures. We show that by employing atomically thin crystals such as …

We derive the plasmon dispersion in doped double-layer graphene (DLG), made of two
parallel graphene monolayers with carrier densities n 1 and n 2, respectively, and an …

Using a structure consisting of two, independently contacted graphene single layers
separated by an ultrathin dielectric, we experimentally measure the Coulomb drag of …

Recent experiments have realized steady-state electrical injection of interlayer excitons in
electron-hole bilayers subject to a large bias voltage. In the ideal case in which interlayer …

Electron-hole bilayers are expected to make a transition from a pair of weakly coupled two-
dimensional systems to a strongly coupled exciton system as the barrier between the layers …

Coulomb drag between adjacent electron and hole gases has attracted considerable
attention, being studied in various two-dimensional systems, including semiconductor and …
