“…Each Bi atom connected with three covalent bonds forms a bilayer (BL) structure. The interaction between the neighbor BL is much weaker than those covalent bonds within the BL structure, resulting in a natural‐layered structure . The crystallographic phases of the obtained films were characterized by X‐ray diffraction (XRD).…”

Ever since discovery of graphene, two‐dimensional (2D) materials become a new tool box for information technology. Among the 2D family, ultrathin bismuth (Bi) has attracted a great deal of attention in recent years due to its unique topological insulating properties and large magnetoresistance. However, the scalable synthesis of layered Bi ultrathin films is rarely been reported, which would greatly restrict further fundamental investigation and practical device development. Here, we demonstrate the direct growth of homogeneous and centimeter‐scale layered Bi films by pulsed laser deposition (PLD) technique. The as‐grown Bi film exhibits high‐purity phase and good crystallinity. In addition, both (111) and (110)‐oriented Bi films can be synthesized by precisely controlling the processing temperature. The characterization of optical properties shows a thickness dependent band gaps (0.075‐0.2 eV). Moreover, Bi thin‐film‐based field‐effect transistors have been demonstrated, exhibiting a large carrier mobility of 220 cm2 V−1 s−1. Our work suggests that the PLD‐grown Bi films would hold the potential to develop spintronic applications, electronic and optoelectronic devices used for information science and technology.

2D crystals are emerging new materials in multidisciplinary fields including condensed state physics, electronics, energy, environmental engineering, and biomedicine. To employ 2D crystals for practical applications, these nanoscale crystals need to be processed into macroscale materials, such as suspensions, fibers, films, and 3D macrostructures. Among these macromaterials, fibers are flexible, knittable, and easy to use, which can fully reflect the advantages of the structure and properties of 2D crystals. Therefore, the fabrication and application of 2D crystal–based fibers is of great importance for expanding the impact of 2D crystals. In this Review, 2D crystals that are successfully prepared are overviewed based on their composition of elements. Subsequently, methods for preparing 2D crystals, 2D crystals dispersions, and 2D crystal–based fibers are systematically introduced. Then, the applications of 2D crystal–based fibers, such as flexible electronic devices, high‐efficiency catalysis, and adsorption, are also discussed. Finally, the status‐of‐quo, perspectives, and future challenges of 2D crystal–based fibers are summarized. This Review provides directions and guidelines for developing new 2D crystal–based fibers and exploring their potentials in the fields of smart wearable devices.

“…Two‐dimensional (2D) materials are a category of materials artificially derived from layered crystals . In the in‐plane directions, the atoms are strongly bonded by covalent or ionic bonds to form atomic layers, while along the out‐of‐plane direction, these atomic layers are weakly held by van der Waals force.…”

Black phosphorus (BP) is a rapidly up and coming star in two‐dimensional (2D) materials. The unique characteristic of BP is its in‐plane anisotropy. This characteristic of BP ignites a new type of 2D materials that have low‐symmetry structures and in‐plane anisotropic properties. On this basis, they offer richer and more unique low‐dimensional physics compared to isotropic 2D materials, thus providing a fertile ground for novel applications including electronics, optoelectronics, molecular detection, thermoelectric, piezoelectric, and ferroelectric with respect to in‐plane anisotropy. This article reviews the recent advance in characterization and applications of in‐plane anisotropic 2D materials.
