Nanowerk January 2, 2018 An international team of researchers (China, Finland) used carbon nanotubes to achieve energy spreads as low as 0.25 eV to demonstrate field-driven ultrafast photo electron emission, in a system capable of much higher phase synchronization than its photon-driven counterpart. According to the researchers, their work will help reshape our understanding of strong field physics, and may very well light the way for entirely new types of electron emission systems. Read more.

Atomically thin perovskites boost for future electronics
Physorg.com December 27, 2017 High-κ dielectric materials may be the key for developing electronic devices of the future. Researchers in Japan created high-performance dielectric nanofilms using 2-D perovskite nanosheets (Ca2Nam−3NbmO3m+1; m = 3–6) as building blocks. It exhibited an unprecedented capacitance density of approximately 203 μF cm-2, which is about three orders of magnitude greater than that of currently available ceramic condensers, opening a route to ultra-scaled high-density capacitors. The research provides a strategy for achieving 2-D high-κ dielectrics/ferroelectrics for use in ultra-scaled electronics and post-graphene technology. Read more.
