A comprehensive library of 2D materials for ink fabrication has been successfully established by the Graphene Flagship’s 2D-PRINTABLE project, covering a broad range of material classes, including p-type and n-type semiconductors, metals, insulators, and functional materials such as ferroelectrics, multiferroics, superconductors, and magnetic 2D compounds.
For selected 2D semiconductors, reliable procedures for controlled p-type and n-type doping, as well as alloying techniques, have been implemented, enabling precise tuning of their electronic and physical properties. Most of these materials were synthesized at scales exceeding 10 g per batch, meeting the requirements for ink formulation and device prototyping. Key materials were further scaled up to 50 g or more, with some compounds produced in quantities ranging from 100 g to 1 kg, demonstrating the robustness and scalability of the developed growth protocols.
The established 2D material library provides a strong foundation for subsequent activities, including exfoliation, ink formulation, and device fabrication, thereby supporting further research and technological development.
