标题： Novel structures of Gallenene intercalated in epitaxial Graphene

摘要： 原子级薄层非剥落材料的制备仍然是一个关键挑战，需要开发创新技术。 在此，通过在碳化硅上生长的外延石墨烯中的插层，利用限制外延实现二维镓。 研究了由镓烯（镓的单层）与石墨烯和碳化硅衬底相互作用产生的新型超结构。 鉴定了不同镓烯相的同时存在，包括b010-镓烯和难以捉摸的高压Ga(III)相。 这项工作揭示了二维镓形成的新的见解，并提供了一个平台来研究受限镓烯的奇异电子和光学性质。 显示英文摘要

摘要： The creation of atomically thin layers of non-exfoliable materials remains a crucial challenge, requiring the development of innovative techniques. Here, confinement epitaxy is exploited to realize two-dimensional gallium via intercalation in epitaxial graphene grown on silicon carbide. Novel superstructures arising from the interaction of gallenene (a monolayer of gallium) with graphene and the silicon carbide substrate are investigated. The coexistence of different gallenene phases, including b010-gallenene and the elusive high-pressure Ga(III) phase, is identified. This work sheds new light on the formation of two-dimensional gallium and provides a platform for investigating the exotic electronic and optical properties of confined gallenene.
