HELLO! I'M andrea.
Andrea recently joined INL as a Marie Curie COFUND Research Fellow. His research is focused on the development of processes for the integration of graphene and two-dimensional materials in high-end technology.
Andrea Capasso is a nanotechnologist with a wide experience in surface science and advanced materials for electronics. He graduated in Electronic Engineering at the University of Roma TRE (Italy) and received a PhD in Nanotechnology at the Queensland University of Technology (Australia) in 2012. Over the last years, he held research position in Australia (QUT), Italy (ENEA and Italian Institute of Technology), and Korea (Yonsei University). During his career, Andrea focused on the production, analysis, and functionalization of carbon-based nanomaterials and two-dimensional crystals, fostering their application in optoelectronics and photovoltaics. His work led to the incorporation of selected nanomaterials in polymeric and perovskite-based solar cells with increased power conversion efficiency and lifetime stability. Andrea was awarded almost €200k in competitive grants and cooperated in several international projects funded by Australian, Italian, and European institutions. He published 30 articles in high-impact journals and 2 book chapters, and gave presentations at more than 30 international conferences on four continents.
The Cofund project
Two-dimensional crystals such as graphene and atomically thin transition metal dichalcogenides offer electronic, optical and mechanical properties of great interest for many fields of technology. The current challenge resides in scaling-up reproducible processes to produce these materials, possibly at affordable cost and with low environmental impact. Chemical vapor deposition theoretically grants full control over the structural and physical characteristics of the crystals, while solution-processing techniques might lead the way towards industrial-scale manufacture. The aim of this project is the implementation of a platform for the integration of two-dimensional crystals into large-area optoelectronic and energy harvesting devices.

Dr Andrea Capasso coordinated a work that was recently published on the Journal of Physical Chemistry C. The article “Ethanol-CVD Growth of Sub-mm Single-Crystal Graphene on Flat Cu Surface” explores the pathway towards a large-scale production of electronic-grade graphene crystals. The material growth is realized by chemical vapor deposition on commercially available copper foil substrates. The substrates are not pre-processed but used as-received to make the process highly reliable and reproducible, as required for industrial production. Graphene crystals with lateral size up to 0.5 mm were used to fabricate microelectronic devices with high performance. This work is representative of Dr Capasso’s current research efforts, which are aimed at bridging the existing gap between fundamental research in 2D materials and commercial technology of interest for the society.
The paper “Electrically Conducting and Mechanically Strong Graphene-Polylactic Acid Composites for 3D Printing”, result of a collaboration between Andrea Capasso and Prof Gwan-Hyoung Lee’s group at Yonsei University (Seoul), is now out on ACS Applied Materials and Interfaces. In this work, the researcher designed and realized an electrically conductive and mechanically reinforced composite for 3D printing. The composite is based on a polylactic acid matrix incorporating graphene nanoplatelets, which provide improved mechanical properties to the polymer (by 44% in tensile strength and 57% in maximum strain) while also granting it electrical conductivity (above 1 mS/cm). The graphene-added composite can be used to 3D-print robust and flexible items, with desired shape and able to conduct current. This paper provides an example of the advancement provided by graphene-based materials in additive manufacturing, such as multifunctional 3D printing technology.
