LIVE DEMO: High-Throughput Mechanical Exfoliation for Low-Cost Production of van der Waals Nanosheets
Yigit Sozen, Juan J. Riquelme, Esteban Zamora, Carmen Munuera y Andres Castellanos-Gomez, investigadores del 2d Foundry del Instituto de Ciencia de Materiales de Madrid (Consejo Superior de Investigaciones Científicas), ofrecerán una demostración en directo sobre uno de los montajes experimentales que han desarrollado para la producción a gran escala y bajo coste de materiales 2D. Aquí tenéis su resumen del evento e información de la localización del mismo.
A method is presented for scaling up the production of flakes of van der Waals materials via mechanical exfoliation. Using a roll-to-roll setup and an automatized, massive parallel exfoliation process, adhesive tapes with a high density of nanosheets of van der Waals materials are produced. The technique allows for obtaining a good trade-off between large lateral size and excellent area scalability, while also maintaining low cost. The potential of the method is demonstrated through the successful fabrication of field-effect transistors and flexible photodetectors in large batches. This low-cost method to produce large area films out of mechanically exfoliated flakes is very general, and it can be applied to a variety of substrates and van der Waals materials and, moreover, it can be used to combine different van der Waals materials on top of each other. Therefore, it is believed that this production method opens an interesting avenue for fabrication of low-cost devices while maintaining a good scalability and performance.
