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. ...
If she hits just the right pitch, a singer can shatter a wine glass. The reason is resonance. While the glass may vibrate slightly in response to most acoustic tones, a pitch that resonates with the material's own natural ...
