The paper discusses the exceptional characteristics and vast usage regarding 2D materials, focusing on advancements other than the widely researched graphene. It studies various 2D materials, like metal oxides, transition metal dichalcogenides, and metal-organic frameworks, which exhibit different electronic and structural properties than graphene [1], [2]. The review outlines the different synthesis methodologies used to obtain few-layer, single-layer, and multilayer assemblies of these materials, in solution and on different substrates, also at wafer scales [3]. This involves the observation of developments in the large-area synthesis technologies which are essential in the process of industrial scalability [4]. Moreover, the article explores the importance of the advanced characterization designs in explaining the atomic structure, electronic band properties and quantum phenomena of these emergent 2D systems [5], [6]. This level of understanding is important in exploiting their distinct electrical, optical, chemical and thermal characteristics in next generation technological uses [7]. The isolation of graphene in 2004 was a turning point and sparked the emergence of the research on 2D materials [8]. This resulting in discovering different novel 2D materials, such as black phosphorus, transition metal dichalcogenides, MXenes, and hexagonal boron nitride which all have a different quantum-confined energy band structure because of the in plane lattice periodicity [9]. The expansion of 2D materials has now gone beyond this to include even wider range of compositions, such as metal oxides, phosphides, and other layered perovskites, and further diversification of their potential applications [10], [11]. This fast-moving era has led 2D materials to develop into a sub-discipline of physical sciences with numerous applications [12].
