Dr.  Teresa Gatti

Senior Researcher


Teresa Gatti holds a master degree in Chemistry from the University of Bologna, Italy (2008) and a Ph.D. in Materials Engineering from Politecnico di Milano, Italy (2014). After postdoctoral activities at the Department of Chemical Sciences of the University of Padova (Italy), since 2019 she is a Junior Research Group Leader at the Center for Materials Research of the Justus Liebig University Giessen (Germany). Since January 2022, she is also an affiliated Senior Researcher at the E3 Centre of Excellence.

She is recipient of the ERC Starting Grant 2021 project JANUS BI. In this project, she will pioneer a method for the synthesis of Janus 2D materials working completely in the liquid phase, by exploiting the liquid-phase exfoliation of layered materials and concepts deriving from asymmetric organic synthesis. The highly asymmetric nanomaterials will be employed for light-energy conversion applications such as photovoltaics and photocatalysis.

Teresa Gatti is also Principal Investigator and WP leader in the H2020 FET-Proactive project LIGHT-CAP. This project targets the realization of photo-capacitors and photo-batteries where the active species are low-dimensional materials (0D nanocrystals and 2D materials).

Dr. Gatti´s research interests cover the production, processing and application in optoelectronic devices of different emerging semiconducting materials, with special attention to species based on non-critical elements and featuring low-environmental impact.

Professor  Vincenzo Giannini

Senior Researcher


Prof. Vincenzo Giannini’s scientific interests rely on theoretical light-matter interactions theoretical linear and nonlinear Plasmonics, Nanophotonics, and Metamaterials. He graduated in Physics from the University of Pisa. Subsequently moved to Spain for a Ph.D. program in Madrid at the Spanish research council (CSIC). The story followed with a postdoc in Amsterdam and a Marie Curie fellowship at the Imperial College London. In June 2014, He started his group at the Imperial College London in the Condensed Matter Theory section, followed by an offer in Spain at the CSIC and finally here at TII.




When light interacts with metal nanoparticles, its conduction electrons can be driven by the incident electric field in collective oscillations known as localized surface plasmon resonances. Plasmonics studies these excitations. Surface plasmons can concentrate or to guide light at the nanometer scale and below the diffraction limit. For this reason, they are extremely relevant in nanophotonic applications as well as in the physics processes where molecules, quantum dots or more generally emitters interact with nanoantennas.​



​Topological insulators are practically the last major surprise in condensed matter physics. They represent a new class of material that we have just discovered. In these materials, the concept of topology plays a fundamental role. For example, they present topological superficial conductive states despite the fact that their bulk is an insulator. Protected states it means that some magnitudes as the electron current can flow only in a particular direction otherwise, it will break time-reversal symmetry. We want to explore how to control 2D directional electron current with light.



Metamaterial is a material which gains its properties from its structure rather than directly from its material composition. Within the context of photonics, such compounds are engineered composites that exhibit superior, designed properties that are not found in nature and not observed in the constituent materials. They have demonstrated many intriguing properties and applications for control over electromagnetic waves such as negative refraction, superlensing, cloaking devices and they have inspired optical nanocircuits, i.e. circuits with nanometric dimension where the signal is the light.
