“…2 (a) that the sliding potential barrier along the armchair direction is greater than the zigzag and 37 0 directions. The potential barriers along the armchair direction and zigzag direction are about 175 meV/cell and 109 meV/cell respectively, which is in good agreement with the previous results [50,51] . The corresponding frictional force along these three directions is shown in Fig.…”

“…Recently, structural superlubricity in phosphorene has been identi ed by means of DFT calculations [50] . Insensitivity of friction of black phosphorus under the high load, which is closely related to its negative Poisson's ratio, has been also studied from rst-principles calculations [51] . Phosphorene shows good performance as a solid lubricant for steel [52] , which attributes to the strong chemical adsorption of phosphorene on the iron/steel surface.…”

Based on the first-principle, the friction anisotropy, structural super-lubricity and oxidation induced ultra-low friction of black phosphorus at atomic scale under different loads have been studied. The results show that the interface friction of black phosphorus is anisotropic, that is, the friction along the armchair direction is greater than that along the zigzag direction. Moreover, the friction between the black phosphorus interfaces shows a structural superlubricity property, and the incommensurate interface friction is approximately one thousandth of the commensurate interface friction, which is mainly due to the less electronic charge and the smaller amplitude of electronic charge change between the incommensurate interfaces during the friction process. In addition, the oxidation of black phosphorus is beneficial for lubrication between interfaces.

“…Similar to the structure of TMDs, atomically thin black phosphorus (BP) has also attracted interest due to its high theoretical mobility, tunable direct band gap and unique bipolar properties, and has potential applications in electronic and optoelectronic devices. [113][114][115][116] Chen et al reported the formation of stable BN-BP-BN heterostructure by encapsulating BP with h-BN. [117] Figure 7g shows the fabrication process of BN-BP-BN heterostructure device with potential self-powered sensing capacities.…”

With the development of the Internet of Things, there is an increasing need for clean energy and large-scale sensory systems. Triboelectric/piezoelectric nanogenerators (TENGs/PENGs), have attracted considerable attention as a new type of power generation terminal, which can harvest surrounding energy and convert it into electrical energy. To improve the output performance of nanogenerators (NGs) and diversify related applications, 2D materials with high carrier mobility and excellent piezoelectric properties can be directly used or integrated as different types of self-powered sensors. In this review, the authors first introduce the excellent piezoelectric and optoelectronic properties of 2D materials, followed by the triboelectric series of 2D materials used in TENGs. The categories of integrated self-powered sensors based on 2D materials are then summarized according to their different structures and compositions. We also discuss in detail the recent applications of integrated self-powered sensors based on 2D materials from five aspects. Finally, the challenges and outlooks in the research field of self-powered sensors are featured. Given the continuous development of self-powered sensors based on 2D materials, they are considered to have significant potential for applications in biomedicine, environmental detection, human motion monitoring, energy harvesting, and smart wearable devices.

“…BP was found to be effective in suppressing the rapid increase in the friction at high loads, with significant friction insensitivity at high loads but relatively poor friction performance at zero loads. 3 Importantly, when investigating the properties of 2D materials such as graphene/h-BN, it is found that phonons play a significant contribution to interlayer friction and thermal transport, [24][25][26][27] and due to the in-plane anisotropy of BP caused by its puckered structure, the transport of phonons in the in-plane and out-of-plane directions is significantly enhanced. 28 Studies have shown that the friction of bilayer BP is usually determined by stacking modes (zigzag-zigzag, zigzag-armchair, armchair-armchair).…”

“…Black phosphorus (BP) is one of the most stable allotropes of phosphorene, 1 which has recently (since 2014) been reevaluated as an important layered material, 2 in which each layer is vertically stacked by van der Waals forces and sheets are easily sheared. 3 BP has a puckered honeycomb structure, unlike other two-dimensional (2D) materials such as graphene and molybdenum disulfide (MoS 2 ). 4 In addition to its special structure, BP also has outstanding physical properties such as limited direct band gap and high carrier mobility at ambient temperature and high light and ultraviolet absorption.…”
