Interface surprises may motivate novel oxide electronic devices

Complex oxides have long tantalized the materials science community for their promise in next-generation energy and information technologies. Complex oxide crystals combine oxygen atoms with assorted metals to produce unusual ...

Using electron beams to encode data in nanocrystals

Ferroelectric materials have an intrinsic electrical polarization caused by a small shift in the position of some of their atoms that occurs below a critical point called the Curie temperature. This polarization can be switched ...

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 ...

Crystals for efficient refrigeration

(Phys.org)—Researchers at the Carnegie Institution have discovered a new efficient way to pump heat using crystals. The crystals can pump or extract heat, even on the nanoscale, so they could be used on computer chips to ...

Ferroelectric memristors may lead to brain-like computers

(Phys.org)—As electrical pulses travel through the body's nervous system, they are passed from neuron to neuron by synapses. A synapse, which consists of a gap junction and the cell membranes of the transmitting and receiving ...
