Scalable and Contamination-Free Selenium-Assisted Exfoliation of Transition Metal Dichalcogenides WSe2 and MoSe2

Processes, Год журнала: 2025, Номер 13(3), С. 791 - 791

Опубликована: Март 8, 2025

In two-dimensional (2D) materials research, exfoliating 2D transition metal dichalcogenides (TMDs) from their growth substrates for device fabrication remains a significant challenge. Current methods, such as those involving polymers, metals, or chemical etchants, suffer limitations like contamination, defect introduction, and lack of scalability. Here, we demonstrate selenium capping-based exfoliation technique. Its advantage lies in its ability to enable the clean, contamination-free transfer TMD films. We successfully exfoliated transferred monolayer multilayer films, including WSe2 MoSe2. The capping layer not only enables seamless but also protects film oxidation, confirmed by X-ray photoelectron spectroscopy Raman spectroscopy. This approach is versatile applicable range TMDs thicknesses, paving way high-quality, scalable integration into nanoelectronic devices.
