“…Thanks to the relatively short BP channel, the PD has a responsivity of 125 mA/W and a dark current of less than 20 nA at 0.5 V bias voltage. Recently, Cao et al built a van der Waals heterostructure based on BP with a 2D chiral perovskite for the first time [182]. The advantages of BP in IR photoelectrons combined with the effective photoabsorption and charge transfer of perovskites in this straightforward heterostructure make the PD's responsivity and optical gain increase by several orders of magnitude compared with BP alone.…”

Two-dimensional (2D) materials have sparked intense interest among the scientific community owing to their extraordinary mechanical, optical, electronic, and thermal properties. In particular, the outstanding electronic and optical properties of 2D materials make them show great application potential in high−performance photodetectors (PDs), which can be applied in many fields such as high−frequency communication, novel biomedical imaging, national security, and so on. Here, the recent research progress of PDs based on 2D materials including graphene, transition metal carbides, transition−metal dichalcogenides, black phosphorus, and hexagonal boron nitride is comprehensively and systematically reviewed. First, the primary detection mechanism of 2D material−based PDs is introduced. Second, the structure and optical properties of 2D materials, as well as their applications in PDs, are heavily discussed. Finally, the opportunities and challenges of 2D material−based PDs are summarized and prospected. This review will provide a reference for the further application of 2D crystal−based PDs.

The unique tribological characteristics of black phosphorus quantum dots (BPQDs) have recently attracted much attention. However, the long-term stable lubrication of BPQDs and prevention of degradation in ultrapure water remain huge challenges. Herein, BPQDs@silica (BPQDs@SiO2) core–shell materials were designed and synthesized. The BPQDs are uniformly distributed in the SiO2 shell. The as-prepared BPQDs@SiO2 as the water-based lubrication additive has remarkable lubricity, wettability, and stability. In particular, compared with the average coefficient of friction (COF) and wear rate of ultrapure water, those of BPQDs@SiO2, being a water-based lubrication additive, could be reduced by 45.7 and 83.0% at 10 N and 150 r/min, respectively. The lubrication mechanisms of BPQDs@SiO2 as a water-based lubrication additive were proposed based on the friction test and wear surface analysis. The excellent lubricity performances of BPQDs@SiO2 are owed to the polishing of the SiO2 shell, the extreme pressure property of the BPQD core, and the tribo-chemical reaction film. This investigation established a simple, convenient, and feasible method for using the BPQDs@SiO2 materials as a water-based lubrication additive. It is expected that BPQDs with a core-shell nanostructure will open up new ideas for the development of excellent lubricating nanomaterials.

“…In addition to linear polarization detection, circular polarization detection provides a new dimension of polarization information, and thus enables a wide range of applications such as anti-jamming imaging [ 5 ], chiral molecule screening [ 6 ], and high-fidelity communication [ 7 , 8 , 9 ]. With the miniaturization of optoelectronic devices and systems [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ], filterless integrated circular polarization detectors are sought to replace traditional devices relying on separate polarizers and wave plates. Flat optics have been proposed to substitute for conventional polarizers and wave plates to reduce the sizes of circular polarization detectors [ 20 , 21 , 22 , 23 , 24 ].…”

Circular polarization detection enables a wide range of applications. With the miniaturization of optoelectronic systems, integrated circular polarization detectors with native sensitivity to the spin state of light have become highly sought after. The key issues with this type of device are its low circular polarization extinction ratios (CPERs) and reduced responsivities. Metallic two-dimensional chiral metamaterials have been integrated with detection materials for filterless circular polarization detection. However, the CPERs of such devices are typically below five, and the light absorption in the detection materials is hardly enhanced and is even sometimes reduced. Here, we propose to sandwich multiple quantum wells between a dielectric two-dimensional chiral metamaterial and a metal grating to obtain both a high CPER and a photoresponse enhancement. The dielectric-metal-hybrid chiral metamirror integrated quantum well infrared photodetector (QWIP) exhibits a CPER as high as 100 in the long wave infrared range, exceeding all reported CPERs for integrated circular polarization detectors. The absorption efficiency of this device reaches 54%, which is 17 times higher than that of a standard 45° edge facet coupled device. The circular polarization discrimination is attributed to the interference between the principle-polarization radiation and the cross-polarization radiation of the chiral structure during multiple reflections and the structure-material double polarization selection. The enhanced absorption efficiency is due to the excitation of a surface plasmon polariton wave. The dielectric-metal-hybrid chiral mirror structure is compatible with QWIP focal plane arrays.
