Highly doped graphene can become superconducting.

Transport characteristics of graphene nanoribbons have implications for nanodevices.

LaAlO3/SrTiO3 interfaces grown by different methods all show a metal-insulator transition, but the observed interfacial electric field strength is not consistent with a widely studied model.

A proposal for how to design a superconducting qubit solves the problem of decoherence caused by randomly charged impurities.

By generalizing the idea of a moveable mirror, it may be possible to observe the dynamical Casimir effect.

Can quantum electronic devices offer an experimental system that mimics the behavior of black holes?

In integer quantum Hall systems, do theory and experiment agree for the wrong reasons?

Can a patterned semiconducting heterostructure yield a better “graphene”?

Giant jumps in the current-voltage characteristics of disordered films could be the first evidence that electron transport in insulators can occur in the absence of phonons.

Random disorder in topological insulators leads to an insulating phase reminiscent of one known for years in two-dimensional systems.

Optical measurements in electron gases at low temperatures and high magnetic fields show the electron spins are, as predicted, polarized, but that this state is surprisingly delicate.

The finding of one-dimensional, topologically protected conducting states on the surface of bismuth suggests the possibility of a quantum spin Hall effect in one dimension.

Measurements of how out-of-equilibrium electrons lose energy along a carbon nanotube reveal that they do not significantly scatter over several microns.

Researchers report the observation of a Kondo effect when charge and spin on a double quantum dot system are entangled.

Researchers explore how the excitonic condensate phase in a bilayer electron gas depends on the relative electron densities of the two layers.

Experiments suggest that one-dimensional behavior is reflected in the transport properties of graphene nanoribbons.

A new study is looking at how disorder affects the conducting states in a topological insulator—revealing one of many ways these unusual materials are different from conventional insulators.

By adsorbing and desorbing nitrogen dioxide, it is possible to add and remove charge carriers from graphene and induce a reversible metal-insulator transition.

Researchers find that tunneling between the two layers of a bilayer two-dimensional electron gas is proportional to their area. Although the result may seem intuitive it poses a challenge to current theory.

The formation of Landau levels in a magnetic field is the hallmark of a two-dimensional electron system, such as graphene. Experiments now suggest that Landau levels can also form in carbon nanotubes.
