Tungsten diselenide emits light with very special properties. Nobody could tell why — but now, scientists have solved the riddle: a combination of atomic defects in the material and microscopic distortion is responsible for the remarkable effect.
Read moreResearchers have fabricated a self-assembled, carbon-based nanofilm where the charge state (ie, electronically neutral or positive) can be controlled at the level of individual molecules. Molecular self-assembly on a metal results in a high-density, 2D, organic quantum-dot array with electric-field-controllable charge state, with the organic molecules used as 'nano-sized building blocks' in fabrication of functional nanomaterials. Achieved densities are an order of magnitude larger than conventional inorganic systems.
Read moreTopological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism, the researchers report.
Read moreThrough a new scanning transmission electron microscopy method, researchers are able to observe electron distribution between atoms and molecules and uncover clues to the origins of ferroelectricity, the capacity of certain crystals to possess spontaneous electric polarization that can be switched by the application of an electric field. The research also revealed the mechanism of charge transfer between two materials.
