The review is devoted to the current state of research in one of the topical areas of the physics and chemistry of two-dimensional materials — the study of atomically thin films. The structure and properties of atomically thin monoelemental films, such as 2D iron, gold, and lithium, as well as silicene, germanene, borophene, etc., are described in detail. Two-dimensional films of metallic compounds like iron, copper, and zinc oxides and iron, cobalt, and copper carbides are considered. The main approaches to the stabilization of monoatomic films inside pores or between layers of other 2D materials are presented, and the exfoliation mechanism of ionic-covalent films with a polar surface into weakly bounded monolayers is described.

该评论致力于二维材料物理和化学的一个主题领域的研究现状——原子薄膜的研究。详细介绍了二维铁、金和锂等原子级薄单元素薄膜以及硅烯、锗烯、硼烯等的结构和性能。考虑了金属化合物的二维薄膜，如铁、铜和锌的氧化物以及铁、钴和铜的碳化物。介绍了在孔内或其他二维材料层之间稳定单原子薄膜的主要方法，并描述了具有极性表面的离子共价薄膜剥离成弱结合单层的机制。
