School of chemistry, University of Manchester, M13 9PL, UK

In this talk I will review ink-jet printable formulations made of 2D materials and their use in heterostructure-based electronics. The talk will present research conducted at the interface between chemistry and electrical engineering: we have developed a general formulation engineering approach to achieve highly concentrated, and inkjet printable water-based 2D crystal formulations, which also provide optimal film formation for heterostructure fabrication [1]. I will provide specific examples of all-inkjet printed devices, such as large area arrays of photosensors on plastic [1], programmable logic memory devices [1], strain sensors on paper [2] and capacitors [3]. If time allows, I will also present the first Hall bar measurements made on printed graphene films.

Prof Cinzia Casiraghi graduated in Nuclear Engineering from Politecnico di Milano (Italy) and received her PhD in Electrical Engineering from the University of Cambridge (UK) in 2006. She was awarded with the Oppenheimer Research Fellowship, followed by the Humboldt Fellowship and the prestigious Kovalevskaja Award (1.6M Euro). In 2008 she became Junior Professor at the Physics Department of the Free University Berlin (Germany). In 2010 she joined the School of Chemistry, at the University of Manchester (UK). Her current research work is focused on the development of 2D inks and their applications in printed electronics, thermoelectrics, and biomedical applications. Furthermore, she is leading expert on Raman spectroscopy, used to characterise a wide range of carbon-based nanomaterials. She authored and co-authored more than 80 peer reviewed articles, collecting more than 22k citations (h-index = 44). She also served as chairperson and program committee member on top international conferences (eg Graphene Week, MRS, etc). She is recipient of the Leverhulme Award in Engineering (2016) and the Marlow Award (2014), given by the Royal Society of Chemistry in recognition of her meritorious contributions in the development of Raman spectroscopy for characterisation of carbon nanostructures.
