The Printed and Molecular Electronics (PME) group the group led by Mario Caironi [LINK] active since 2010 in the Center for Nano Science and Technology @PoliMi (CNST) of the Istituto Italiano di Tecnologia. PME aims at improving the knowledge on the opto-electronic properties of solution-processable semiconductors, in particular conjugated organic materials, and at taking full advantage of their printability in order to deliver applications in the large-area and flexible electronics fields. We are therefore interested in clarifying charge injection and transport properties in thin films of semiconducting polymers, but also in self-assembled monolayers, in order to build a rationale that would allow engineers to control these properties in electronic devices such as field-effect transistors, photodetectors, solar cells and a wide range of sensors. More recently we are active in the field of organic thermoelectrics and edible electronics. From an application point of view, we are interested in developing processes that could enable the wide-spread applications of flexible electronics, overcoming current limits in scalability, resolution and reliability.

Our activity therefore spans from the investigation of fundamental properties, where we are led by curiosity, to applications, which is our final goal.

If you are interested in what we do, you are most welcome to get in touch with us!

Laboratories

[object Object]

PME Group lab facilities are hosted at the Center for Nano Science and Technology of Istituto Italiano di Tecnologia in Milan. The main labs are the WETLAB and the Electrical Characterization lab.
The WETLAB is a grey room for device manufacturing equipped fumehoods and gloveboxes. Printing tools for device manufacturing include: two inkjet printers, a bar/knife coater, a Slot-die coater, a Screen Printer a spray coater. It is also provided with an inner Class 1000 clean room for lithography.
The Electrical Characterization Lab is equipped with everything is needed for the full characterization of devices: electrical probe stations in air, nitrogen and vacuum, semiconductor parameter analyzers and a high-frequency prober (up to 10 GHz). Custom setups for photodetectors measurements are present.
