Imaging ferroelectric domains

(Phys.org) —When thin films of ferroelectric materials are grown on single-crystal substrates, they can develop regions of aligned polarization—called "domains"—that often adopt complex patterns. Manipulation of ferroelectric ...

Making big leaps in understanding nanoscale gaps

Creating novel materials by combining layers with unique, beneficial properties seems like a fairly intuitive process—stack up the materials and stack up the benefits. This isn't always the case, however. Not every material ...

New quasiparticle discovered in moiré patterns

If you hold one wire mesh on top of another one and look through it, you'll see a larger pattern called a moiré pattern formed by the overlapping grids of the two meshes, which depends on their relative twisted angle. Scientists ...

Scientists break record for thinnest light-absorber

Stanford University scientists have created the thinnest, most efficient absorber of visible light on record. The nanosize structure, thousands of times thinner than an ordinary sheet of paper, could lower the cost and improve ...

Iron-platinum alloys could be new-generation hard drives

Meeting the demand for more data storage in smaller volumes means using materials made up of ever-smaller magnets, or nanomagnets. One promising material for a potential new generation of recording media is an alloy of iron ...
