Researchers from Universidad Autónoma de Madrid (UAM) and Instituto de Física de la Materia Condensada (IFIMAC) have developed a new technique for fabricating nanoelectrodes for the characterization of electrical transport properties at the nanoscale.

Identifying the two-dimensional (2D) topological insulating (TI) state in new materials and its control are crucial aspects towards the development of voltage-controlled spintronic devices with low-power dissipation.

The ultra-relativistic nature of electrons in graphene relates to a topological property of their wave-functions.

We predict that long-lived excitons with very large binding energies can also exist in a single or few layers of monochalcogenides such as GaSe.

Graphene is a wonder material that possesses many outstanding properties, including extraordinary strength, stiffness and high flexibility, which make it a very good candidate to withstand ultrahigh pressure.
