Special Issue Information

Dear Colleagues,

Since the discovery of graphene in 2004, two-dimensional (2D) materials have attracted considerable attention in the past decade. The atomically thin thickness and van der Waals (vdWs) interaction between adjacent layers endow 2D materials with unique layer-dependent electrical, optical, and mechanical properties. With the rapid expansion of 2D groups in recent years, 2D materials have been applied in various fields, such as electronics, optoelectronics, biomedicine, catalysis, and energy storage. Compared to conventional materials, 2D devices not only possess a small size and tunable features but also exhibit remarkable performance and potential to develop real applications. This Special Issue of Applied Sciences aims to present original articles on the applications, performance, and future trends of 2D materials, providing a platform to share ideas and improve the investigation of the development of practical 2D devices. Both original research and review articles are welcomed in this issue.

Defects are an integral part of the structure of various two-dimensional materials (2D), including 2D transition-metal dichalcogenides. These defects usually govern their electronic properties. In this work, simulations based on the density functional theory are employed for a comprehensive characterization of typical point defects in the T–VSe2 and H–VSe2 monolayers. Specifically, Se and V monovacancy defects are studied. The formation of monovacancies in T–VSe2 and H–VSe2 monolayers are found to be less favorable than in other common transition-metal dichalcogenides. Meanwhile, Se and V monovacancy defects tune the electronic structure of the T–VSe2 and H–VSe2 monolayers significantly. The scanning tunneling microscopy simulated images obtained could facilitate the detection of monovacancies in T–VSe2 and H–VSe2 monolayers in experiments. Full article

The emergence of phosphorene has generated significant interest in 2D group VA nanomaterials. Among this group, bismuthene exhibits layer-dependent direct bandgaps, high carrier mobility, and topological insulator properties because of its unique structure and ultrathin nature, distinguishing it as a promising candidate for photonic applications. Particularly, its outstanding stability in air makes bismuthene more advantageous than phosphorene for practical applications. Here, we provide a comprehensive review of recent advances regarding 2D bismuth by focusing on the aspects of methods of synthesis and photonic applications. First, the structure and fundamental properties of bismuthene are described, referring to its crystallinity and band structures, as well as to its nonlinear optical properties. Subsequently, the common synthesis methods for 2D bismuth are summarized, including both top-down and bottom-up approaches. Then, potential photonic applications based on 2D bismuth, involving nonlinear photonic devices, photocatalyst, and photodetectors, are illustrated. The performance, mechanisms, and features of the devices are discussed. Finally, the review is summarized and some challenges and future outlooks in this field are addressed. Full article
