The project is progressing successfully, with major achievements across all work packages. Novel 2D materials have been synthesized and functionalized, yielding promising results. Ink formulation and printing techniques have enabled the creation of high-performance devices, while advanced characterization methods have provided deep insights into material properties and network structures. Electrical characterization has optimized charge transport in printed networks and heterostructures, enhancing device performance.
The collaboration with the Graphene Flagship and engagement with stakeholders have increased the project's visibility and impact. Synthesis efforts involved screening nearly one million compounds, identifying over 2000 exfoliable materials, and synthesizing 3D crystals to produce more than 100 layered compounds. Liquid-phase exfoliation techniques successfully generated high-quality nanosheets suitable for industrial production.
Functionalization strategies, such as controlled oxidation and thiol functionalization, improved stability and surface properties, while non-covalent functionalization enhanced colloidal stability. Microfluidic approaches helped construct in-plane heterostructures, strengthening interflake coupling. Ink formulation optimizations led to record mobility in devices, with advanced deposition methods producing pinhole-free heterostructures.
Comprehensive characterization using AFM, SEM, TEM, XPS, Raman, and advanced spectroscopies enabled detailed analysis of nanosheets and interfaces. Electrical studies using impedance spectroscopy and KPFM informed charge transport improvements. Device fabrication successes include high-capacitance capacitors and high-mobility TFTs, with ongoing work on light-sensitive devices and LEDs.
Robust dissemination, including publications and outreach, combined with effective project management, has ensured smooth coordination and quality assurance, keeping the project on track to meet its goals.
