Title: Optics on nano-structured surfaces
Biography: Valerio Pruneri
Ultrathin materials and nano-structuring are becoming essential for the functionalization of optical surfaces. In the talk we will show how ultrathin metals can be exploited to create competitive transparent electrodes while graphene and phase change materials to modulate the optical response. Ultrathin metals can also be used to create nanostructured surfaces through mass scalable dewetting and etching techniques. We will also provide examples of applications enabled by these materials and techniques, including efficient high speed electro-optic modulators, indium-free light emitting diodes, solar cells and easy-to-clean display screens.
