Web6 apr. 2024 · Abstract. Extreme ultraviolet (EUV) radiation is a key technology for material science, attosecond metrology, and lithography. Here, we experimentally demonstrate metasurfaces as a superior way to focus EUV light. These devices exploit the fact that holes in a silicon membrane have a considerably larger refractive index than the surrounding ... WebPhD degree in physics, applied physics, materials science, electrical- / electronics engineering, or related fields. Laboratory experience in UHV techniques, and/or cleanroom processing, including device nanofabrication. Experience in lithography and etching techniques will be advantageous.
