  • 'White graphene' to the rescue
    It is being suggested that white graphene may be the perfect solution for silicon as a new era unfolds in nanoscale electronics.
  • Ferromagnetic semiconductor GaMnAs
    The newly-developing spintronics technology requires materials that allow control of both the charge and the spin degrees of freedom of the charge carriers. Ferromagnetic semiconductors (SC) are considered suitable due to simultaneous presence of magnetic order and of semiconducting properties. GaMnAs is one of the most intensively studied ferromagnetic SC. In this paper we will review recent research and accomplishments regarding two technologically important properties – magnetic anisotropy and interlayer coupling — of GaMnAs-based multilayer structures, with an eye on their potential role in practical devices.

The carbon new age

Graphene has been considered by many as a revolutionary material with electronic and structural properties that surpass conventional semiconductors and metals.

Due to its superlative qualities, graphene is being considered as the reference material for a post-CMOS technology. Furthermore, graphene is also quite unusual electronically since its electric carriers behave as if they were massless and relativistic, the so-called Dirac particles. Because of its exotic electronic properties, theorists are being forced to revisit the conceptual basis for the theory of metals. Hence, graphene seems to be unveiling a new era in science and technology with still unseen consequences.
