DESCRIPTION:Speaker: Maria Kandyla (National Hellenic Research Foundation)
   The need for advanced materials and systems with new functionalities ha
 s motivated the development of micro/nanostructures on solid surfaces\, wh
 ich are necessary for the fabrication of functional devices for novel appl
 ications. In this talk\, we will discuss the development of functional mic
 ro/nanostructures\, based on laser-processed surfaces. Coating micro/nanos
 tructures with thin metallic films results in plasmonic substrates with en
 hanced electromagnetic response across the entire visible range\, which ar
 e used for plasmonic optical trapping [1]. Combining silicon micro/nanostr
 uctures with thin semiconducting films results in electronic heterojunctio
 ns with increased surface area for improved optoelectronic performance [2]
 . Furthermore\, isotype heterojunctions result in wavelength-selective\, h
 igh-speed photodetectors with self-powered operation\, which can be furthe
 r engineered by careful selection of the electronic properties of the cons
 tituting materials [3\,4]. “Smart” surfaces of controllable extreme we
 tting states are obtained by combining photoresponsive metal oxides with l
 aser-processed micro/nanostructured substrates\, which can reach complete 
 water repellence without chemical modification [5]. Also\, surfaces with c
 ontrolled topography\, either at the micro- or at the nano-scale\, for tar
 geted cell cultures for biomedical applications [6]. We will present recen
 t advances in these fields and discuss future applications. References 	 D
