(Phys.org)—Optoelectronic devices that combine electronics and photonics are incorporating two-dimensional (2D) materials for a range of applications. At the same time, cooperative phenomena – in which a system's individual ...
(Phys.org)—New research by a group from Hokkaido University in Japan has shown that the plastic ionic crystal, quinuclidinium perrhenate, has ferroelectric properties and can serve as a model for finding new plastic ionic ...
An electronic device that could lead to smaller, low-power memory chips can now be controlled and probed by light, as revealed by research from KAUST.
