Graphene records infraslow brain waves

Arrays of graphene microtransistors are used to record infraslow cortical brain activity. The reduced signal drift and the array compatibility with optical imaging techniques make these devices useful for monitoring of brain physiology.

  • Editorial |

    Much academic and industrial effort has been devoted to the study of multiferroics, but if related technologies are to have real-world impact, market awareness and reproducibility are also key.


  • Comment |

    Topological structures have considerable potential in nanoelectronics and new device concepts. They are key to the design and understanding of novel functionalities in ferroic materials — that is, materials that have one or more types of built-in order such as magnetic, ferroelectric, ferroelastic and multiferroic materials.

    A hybrid state of photons and electronic excitations in semiconductor quantum wells shows nonlinear behaviour at the level of single or few quanta, thus opening the door to the realization of photonic nonlinear quantum devices employing semiconductor technologies.

Review Articles

  • Review Article |

    Magnetoelectric multiferroics, where magnetic properties are manipulated by electric field and vice versa, could lead to improved electronic devices. Here, advances in materials, characterisation and modelling, and usage in applications are reviewed.

  • Letter |

    Confined exciton–polaritons in semiconductor-based quantum wells can give rise to correlations slightly below the level of classical coincidence counts under resonant excitation, such that single or few polariton excitations are sufficient to modify the statistics of the radiation going through the system.
