Trenches, craters and hillocks: shapes and structures which are observed after meteorite impacts can also be found on a nanoscale, when crystals are bombarded with heavy ions. Understanding the physics of those nano-impacts helps scientists to create new ...

Image: Juan M. Merlo/Boston College This image shows the cavities where a three-step conversion process—from surface plasmon to photon and back to surface plasmon—takes place. Currently, wireless optical communication on computer chips occurs at near ...
In nanoscale electronic devices, electrons must gain a certain level of charging energy in order to tunnel across a barrier. When one electron manages to gain this energy and tunnel, it blocks the simultaneous tunneling of other electrons because ...
(Nanowerk Spotlight) Localization of photons to nanoscale volumes with the aid of plasmonic nanoantennas opened new horizons in bio(chemical) sensing and nanoscale imaging. However, plasmon resonances are short-lived, and the photon energy quickly ...
