Scientists explored the fundamental physics of the world's best thermoelectric material - tin selenide - using neutron scattering and computer simulations. Their new understanding of the origin of atomic dynamics in this material may aid research in energy sustainability and enable the design of materials that efficiently convert heat into electricity.
A low-cost, high-speed method for printing graphene inks using a conventional roll-to-roll printing process, like that used to print newspapers and crisp packets, could open up a wide range of practical applications, including inexpensive printed electronics, intelligent packaging and disposable sensors.
Researchers have demonstrated a new hybrid system that is a promising candidate as a building block for quantum computation, showing a way to couple a natural phosphorus atom with an artificial atom called a quantum dot.
Nanoparticles with sizes the order of a wavelength interact with light in specific ways. Researchers are inquiring how to use arrangements of such nanoparticles to improve solar cells and other opto-electronic devices.
Physicists have discovered magnetic disturbances in 2-D superconductor layer, resembling little oscillating stars; these star-like excitations are caused by a single magnetic atom put into the layer of superconducting material.
