SUMMARY:Laserlab-Europe Talk: Laser processing of functional micro/nanostructures for photonics\, optoelectronics\, and smart surfaces\, 25 Feb 2026
DESCRIPTION:Speaker: Maria Kandyla (National Hellenic Research Foundation)  \nThe need for advanced materials and systems with new functionalities has motivated the development of micro/nanostructures on solid surfaces\, which are necessary for the fabrication of functional devices for novel applications. In this talk\, we will discuss the development of functional micro/nanostructures\, based on laser-processed surfaces. \nCoating micro/nanostructures with thin metallic films results in plasmonic substrates with enhanced electromagnetic response across the entire visible range\, which are used for plasmonic optical trapping [1]. Combining silicon micro/nanostructures with thin semiconducting films results in electronic heterojunctions with increased surface area for improved optoelectronic performance [2]. Furthermore\, isotype heterojunctions result in wavelength-selective\, high-speed photodetectors with self-powered operation\, which can be further engineered by careful selection of the electronic properties of the constituting materials [3\,4]. “Smart” surfaces of controllable extreme wetting states are obtained by combining photoresponsive metal oxides with laser-processed micro/nanostructured substrates\, which can reach complete water repellence without chemical modification [5]. Also\, surfaces with controlled topography\, either at the micro- or at the nano-scale\, for targeted cell cultures for biomedical applications [6]. We will present recent advances in these fields and discuss future applications. \nReferences \n\n	 \nD.G. Kotsifaki\, M. Kandyla\, and P.G.
