Research summary

My research interests are at the interface between science and engineering. In specific, my research efforts aim to develop novel applications of atomically thin materials beyond graphene, which strongly interact with light.

Owing to their atomically thin nature these materials present unconventional

mechanical, optical and electrical properties, which make them promising for a variety of applications from energy storage to electronics on flexible substrates and photonics. My overall objective is to establish a new paradigm in materials science, where device characteristics will be the result of the synergistic combination of hierarchical assembly and the intrinsic properties of individual two-dimensional units.

I am currently focusing my attention on three materials (WS2, MoS2 and WSe2), which share properties with graphene but also retain key complementary characteristics. Unlike graphene, they can efficiently emit light in the visible-near IR range if they are three-atom thick only. All these characteristics make them unique materials to be integrated in future semitransparent opto/electronics on flexible/stretchable substrates and photonics-based communication systems. Devices on plastic/rubber substrates are at the cutting-edge of current technologies which see application from medical diagnostics to consumable electronics. These technologies can have a huge impact in the society, revolutionizing communication, medical diagnostics, and generating novel conceptions of human machine interfaces. Along with devices development, my interest is centered also in making these materials widely available, therefore in developing scalable synthesis routes.

I are developing methods to produce these materials in large amount in water and to structure them to form 3D objects with multifunctional properties. Water is a safe solvent to store nanometric crystals and also enable easy manipulation for direct incorporation into devices and for 3D structuring.
