Cuprates (copper oxides) are currently used as highest temperature (-135° C) superconductors. Scientists are trying to find new candidates for which this temperature would be even higher. This involves understanding in detail the electronic mechanisms involved between the elements composing the sup...

Ferroelectric memories - in which information is coded within the direction of the electric polarization – are energy saving, durable and very fast electronic devices already commercially available. However, reading the information necessitates an auxiliary electronic circuit which limits the mini...

Control of polarization is a key issue in research on ferroelectrics materials and its possible use for low-consumption electronic devices. A ferroelectric material spontaneously show microscopic domains with different polarization directions to minimize its energy. We showed very low energy electro...

Ferroelectric devices could be an alternative to magnetic based memories for future high-density data storage. Such devices have considerable advantages: they are non-volatile, have fast read-write times, low energy consumption and use realistic voltages. However, before considering future applicati...

An ideal ferroelectric (FE) must be an insulator to show a spontaneous polarization, however, recent theoretical and some experimental work suggests that a ferroelectric state can exist up to a certain critical doping level. Thus the possibility of coexistence of ferroelectricity and d electron occu...
