3D printing of molecular electronic devices. We aim to explore the possibilities of self-assembly and supramolecular chemistry in bottom-up nanofabrication to obtain devices that are organized at the molecular level. The challenge is to form electrical contacts to these molecular assemblies. We have developed various methods to form electrical contacts to monolayers of safely to yield electrode—monolayer—electrode junctions based on a non-Newtonian liquid-metal (biocompatible alloy of Ga and In), but it is important to improve scaling. One way to achieve this is by 3D printing of liquid-metal, which has been developed by previous HMOE BSc projects. The next-step is how to develop this into cross-bar arrays: How does printed liquid-metal contact with molecules? How do these devices perform electrically and optically?
