Atomic whirls open potential applications in data processing

Abstract

Opportunities for ultrahigh speed and density information processing open up with the discovery of nanoscale atomic whirls induced by electric field stimuli. Scientists from the Institute of Physics contributed to a study uncovering how polarization whirls react to THz pulses on the nanometre scale, which was published in the April 15th issue of 

From superlattices to supercrystals

Abstract

FZU researchers, in a world-wide collaboration led by Dr. Pavlo Zubko from University College London, have found that in superlattices, composed of layers of a ferroelectric material separated by thin metallic spacers, electric dipoles form an unusual pattern of nanoscale domains that order in three dimensions to create a ‘domain supercrystal’, exhibiting outstanding dielectric response.
