Phase Change Materials with Tunable Optical and Electrical Properties for Photonics and THz Programmable (Meta) devices

We present our current researches on phase transition materials (vanadium dioxide, VO2) performing a thermally- or electrically-triggered metal-insulator transition and on chalcogenide amorphous-to-crystalline phase change materials like GeTe or Ge₂Sb₂Te₅ and we will focus on their tunable electrical and optical properties for applications in different domains spanning from DC to millimeter waves, THz and optics.
