Phase Change Metasurfaces by Continuous or Quasi-Continuous Atoms for Active Optoelectronic Integration.

In recent decades, metasurfaces have emerged as an exotic and appealing group of nanophotonic devices for versatile wave regulation with deep subwavelength thickness facilitating compact integration. However, the ability to dynamically control the wave-matter interaction with external stimulus is highly desirable especially in such scenarios as integrated photonics and optoelectronics, since their performance in amplitude and phase control settle down once manufactured. Currently, available routes to construct active photonic devices include micro-electromechanical system (MEMS), semiconductors, liquid crystal, and phase change materials (PCMs)-integrated hybrid devices, etc.

Molecular Bonding of Predissociative CO on Fe(100): Molecular Orbital Perspective.

On Fe(100), CO molecules can get activated efficiently so that CO bond breaking occurs with its transition state in close connection to the adsorbate. The CO bonding thus serves as a prototype model, nicely representing a balance of two simultaneous processes, namely, bond making with the surface and bond breaking within the adsorbate. Such unique configuration highlighting the interplay of two fundamental processes in one adsorption geometry, about which chemists have often fantasized, provides a viable solution to understand the very fundamental aspects of chemistry exemplified in a broad range of disciplines.
