- 27/04/2021 Identification of the wettability of graphene layers at the molecular level Graphene is a two-dimensional material in which carbon atoms are arranged in hexagonal structures, and it has unique physical and chemical properties such as sub-nanometer thickness, chemical stability, mechanical flexibility, electrical and thermal conductivity, optical transparency, and selective permeability to water. Due to these properties, various applications of graphene in transparent electrodes, desalination, electrical energy storage, and catalysts have been vigorously studied.
- 22/04/2021 Oxygen migration enables ferroelectricity on nanoscale Hafnium-based thin films, with a thickness of only a few nanometres, exhibit an unconventional form of ferroelectricity. This allows the construction of nanometre-sized memories or logic devices. However, it was not clear how ferroelectricity could occur at this scale. A study that was led by scientists from the University of Groningen showed how atoms move in a hafnium-based capacitor: migrating oxygen atoms (or vacancies) are responsible for the observed switching and storage of charge. The results, which were published online by the journal Science on 15 April, point the way to new ferroelectric materials.
