Using in-situ microscopy to follow the intercalation process of caesium of graphene monolayer on iridium surface, scientists discovered a novel mechanism for intercalation and entrapment of alkali atoms under epitaxial graphene.
Scientists have found a creative way to radically improve thermoelectric materials, a finding that could one day lead to the development of improved solar panels, more energy-efficient cooling equipment, and even the creation of new devices that could turn the vast amounts of heat wasted at power plants into more electricity.
The understanding of advanced materials and how they perform under different conditions will be enhanced thanks to a new research collaboration between the Science and Technology Facilities Council (STFC) and the National Physical Laboratory (NPL).
While pursuing the goal of turning a cloud of ultracold atoms into a completely new kind of circuit element, physicists have demonstrated that such a cloud - known as a Bose-Einstein condensate - can display a sort of 'memory'.
The future of computing may lie not in electrons, but in photons -- in microprocessors that use light instead of electrical signals. But these photonic devices are typically built using customized methods that make them difficult and expensive to manufacture. Now, engineers have demonstrated that low power photonic devices can be fabricated using standard chip-making processes. The team dubs this a major milestone in photonic technology.
