Black Phosphorus Rediscovered: From Bulk Material to Monolayers

2017

Phosphorus is a nonmetal with several allotropes, from the highly reactive white phosphorus to the thermodynamically stable black phosphorus (BP) with a puckered orthorhombic layered structure. The bulk form of BP was first synthesized in 1914, but received little attention until it was rediscovered in 2014 as a member of the new wave of 2D layered nanomaterials. BP can be exfoliated to a single sheet that acts as a semiconductor with a tunable direct band gap, a high carrier mobility at room temperature, and an in-plane anisotropy. The development of BP applications is hampered by surface degradation, thus efforts to achieve effective BP passivation are ongoing, such as its integration in van der Waals heterostructures. BP has been tested as a novel nanomaterial in batteries, transistors, sensors, and photonics. This Review begins with the origin of the BP story, following the path from a bulk material to modern few/single layers. The physical and chemical properties are summarized, and the state-of-the-art of BP applications highlighted.

“…In addition to graphene, there are an extremely large number of 2D layered materials, such as transition metal oxides (TMOs), transition metal dichalcogenides (TMDs), group IIIA, IVA, IVB, ternary metal chalogenides, few‐layer black phosphorus (BP), that show prominent electronic and optoelectronic properties different from their 3D counterparts and have been widely explored in the fields of photonics and optoelectronics . Compared with traditional 3D semiconductors, these 2D layered materials, in particular TMDs and few‐layer BP, present plenty of great advantages for photodetection.…”

Flexible photodetectors have attracted a great deal of research interest in recent years due to their great possibilities for application in a variety of emerging areas such as flexible, stretchable, implantable, portable, wearable and printed electronics and optoelectronics. Novel functional materials, including materials with zero-dimensional (0D) and one-dimensional (1D) inorganic nanostructures, two-dimensional (2D) layered materials, organic semiconductors and perovskite materials, exhibit appealing electrical and optoelectrical properties, as well as outstanding mechanical flexibility, and have been widely studied as building blocks in cost-effective flexible photodetection. Here, we comprehensively review the outstanding performance of flexible photodetectors made from these novel functional materials reported in recent years. The photoresponse characteristics and flexibility of the devices will be discussed systematically. Summaries and challenges are provided to guide future directions of this vital research field.

“…2019, 6,1901837 property for better applications. [197] When applied into 2D photodetectors, they greatly improved photoelectrical properties with remarkably increased responsivity from 0.765 to 15.33 A W −1 , i.e., 20-fold enhancement compared to pristine BP. [195] Further, 7,7,8,8-tetracyano-p-quinodimethane on BP nanosheets offered electron-withdrawing property to render electron transfer from BP to organic moiety, [193] leading to a low on-state resistance (3.2 Ω mm), and thus high field-effect mobility (229 cm 2 V −1 s −1 ) and drain current (532 mA mm −1 ).…”

The discovery of graphene and subsequent verification of its unique properties have aroused great research interest to exploit diversified graphene‐analogous 2D nanomaterials with fascinating physicochemical properties. Through either physical or chemical doping, linkage, adsorption, and hybridization with other functional species into or onto them, more novel/improved properties are readily created to extend/expand their functionalities and further achieve great performance. Here, various functionalized hybridizations by using different types of 2D nanomaterials are overviewed systematically with emphasis on their interaction formats (e.g., in‐plane or inter plane), synergistic properties, and enhanced applications. As the most intensely investigated 2D materials in the post‐graphene era, transition metal dichalcogenide nanosheets are comprehensively investigated through their element doping, physical/chemical functionalization, and nanohybridization. Meanwhile, representative hybrids with more types of nanosheets are also presented to understand their unique surface structures and address the special requirements for better applications. More excitingly, the van der Waals heterostructures of diverse 2D materials are specifically summarized to add more functionality or flexibility into 2D material systems. Finally, the current research status and faced challenges are discussed properly and several perspectives are elaborately given to accelerate the rational fabrication of varied and talented 2D hybrids.
