'Giant' charge density disturbances discovered in nanomaterials

more »

German researchers have, with the help of computer simulations, discovered a combination of materials that strengthens the so-called Friedel oscillations and bundles them, as if with a lens, in different directions. With a range of 50 nanometers, these 'giant anisotropic charge density oscillations' are many times greater than normal and open up new possibilities in the field of nanoelectronics to exchange or filter magnetic information.
