Newly developed atomic engineering techniques have opened exciting opportunities for enabling ferroelectric behavior in high-k dielectrics, materials that have a high dielectric constant (i.e., kappa or k) compared to silicon. ...
The potential of an ultrafast form of transmission electron microscopy to measure sound waves in nanostructures has been demonstrated by three RIKEN physicists. This could help realize a high-resolution imaging method that ...
