2DCC CHet system enables synthesis of 2D metals, alloys, and functionalized graphene
Confinement heteroepitaxy (CHet) is an emerging approach for stabilizing atomically thin metals and alloys that normally prefer to form 3D structures by confining their growth at interfaces such as graphene. This enables access to truly two-dimensional metallic phases with unusual electronic and optical properties. This opens new directions in quantum materials and nanoscale device engineering.
The 2DCC CHet platform supports these studies by providing a controlled, high-purity environment for creating both 2D metals and alloys, while elevated substrate temperatures and rotation promote uniform heteroepitaxy. The system’s pressure control and ultra-low base pressure ensure clean growth conditions, and integrated ion and plasma sources allow for defect engineering and surface functionalization, particularly in graphene confinement layers. With available process gases such as N₂, Ar, H₂-containing mixtures, and O₂, the platform can also probe reactive growth pathways and interface chemistry. Altogether, this setup enables systematic exploration of 2D metal synthesis, alloy design, defect tuning, and heterostructure formation, supporting research spanning catalysis, nanoelectronics, and fundamental surface science.
