Project description
Novel deposition technology for organic molecules opens doors for nanoelectronics
The combinations of materials may seem limitless when one attempts to integrate the best properties of two or more for certain applications. However, the reality is that processability – or lack of it – can form an insurmountable barrier to the development of novel composite designs. Until now, the deposition and organisation of molecules on substrates under vacuum with atomic precision heavily relies on sublimable materials. The EU-funded MOLShuttle project is developing a versatile and efficient capability towards bringing thermolabile organic and biological molecules on well-defined interfaces, opening the door to the wealth of functionalities present in these molecules. The technology will enable routine realisation of previously inaccessible nanoarchitectures for applications in numerous fields.
Objective
"Current strategies to fabricate novel materials are commonly constituted on composite designs, ideally engineered with atomic precision. Tremendous prospects exist for nano-electronics integrating functional molecules and nano-architectures, such as the nano-graphene family. By depositing tailored molecules on well-defined interfaces in vacuum, novel sophisticated structures and device elements come in reach. However, typical deposition processes with atomic finesse are limited to thermostable sublimable molecules, excluding many organics and almost all biomolecules with their fascinating properties. Our SoftBeam system fills this gap. Inspired by the 2D-INK FET project, we shall realize a versatile tool based on cutting-edge technology to deposit solvable species, irrespective of fragility aspects, on a given template in a highly-controlled manner. To reach full flexibility and a broad R&D community we propose a) to develop an innovative ""portable preparation port""- a station to transfer the deposition yield to a desired analytical system such as scanning probe or electron microscopy, x-ray spectroscopy or synchrotron, and b) to integrate the system by refinement of the spray step and vacuum setup, while keeping vacuum, temperature control, and performance at lower expenses. SoftBeam will allow efficient and flexible handling of a plethora of complex species, which could not be processed with the methods applied in the 2D-INK project. Combining an innovative deposition method and the 2D-INK's holistic approach, we shall establish a next-generation instrumental platform for realizing unprecedented nano-architectures. Value to FET-project’s potential is obvious: While the initial aim on the development of novel materials remains, a new dimension is reached by the introduction of a potentially disruptive fabrication method. These measures will foster EU region and benefit a wide spectrum of end-users in nanotechnology, biotech, material science, chemistry and physics."
