New Publication in Science Liquid-liquid phase transition in super-cooled phase-change materials

[14.06.2019] Phase-change materials (PCMs) are used in the latest generation of smartphones enabling higher storage densities and energy efficiency. When an electrical or optical pulse is applied to heat these materials locally, they change from a glassy to a crystalline state, and vice versa. (...)

New Publication in ACS Photonics Focusing Surface Plasmons with Fresnel-Zones

[26.02.2019] In the 19th century, Augustin Jean Fresnel invented his zone-plate; basically a hologram, which - by diffraction - forms a defined focal point if illuminated with a plane light wave. Frank Meyer zu Heringdorf's  TR-PEEM Team has now applied the concept of Fresnel-focusing to surface-plasmon-polaritons, i.e., to electron-density waves that can propagate at metal surfaces with almost the speed of light in vacuum.
