“…The critical size of field effect transistors (FETs) is aggressively scaled down to the nanometer regime to acquire higher chip density, higher speed, and lower power consumption 3,4. Among the low‐dimensional materials, 2D layered materials5 such as graphene,6 black phosphorus (BP),7–9 and transition metal dichalcogenides (TMDCs)10 have been widely investigated for their potential development in future electronics and optoelectronics technology due to their unique physical, chemical, optical, and electronic properties. As carrier transport is confined in plane, 2D layered materials are considered as promising candidates for high‐mobility “tunnel‐electronic” devices.…”

Layered metal monochalcogenides have attracted significant interest in the 2D family since they show different unique properties from their bulk counterparts. The comprehensive synthesis, characterization, and optoelectrical applications of 2D‐layered tin monosulfide (SnS) grown by pulsed laser deposition are reported. Few‐layer SnS‐based field‐effect transistors (FETs) and photodetectors are fabricated on Si/SiO2 substrates. The premium 2D SnS FETs yield an on/off ratio of 3.41 × 106, a subthreshold swing of 180 mV dec−1, and a field effect mobility (µFE) of 1.48 cm2 V−1 s−1 in a 14‐monolayer SnS device. The layered SnS photodetectors show a broad photoresponse from ultraviolet to near‐infrared (365–820 nm). In addition, the SnS phototransistors present an improved detectivity of 9.78 × 1010 cm2 Hz1/2 W−1 and rapid response constants of 60 ms for grow‐time constant τg and 10 ms for decay‐time constant τd under extremely weak 365 nm illumination. This study sheds light on layer‐dependent optoelectronic properties of 2D SnS that promise to be important in next‐generation 2D optoelectronic devices.

“…[18,19,39,40] Very recently, our group has demonstrated an efficient, facile, and extremely fast (<12 min) production method for high-quality, FL-BP flakes using microwave-assisted LPE. [15,41] Zhang et al [15] were the first to report the preparation of BPQDs with an average size of 4.9 nm and lattice fringes of 0.34 nm (Figure 1l) and 0.52 nm (Figure 1m), which can be ascribed to the (021) and (020) planes of BP crystal, respectively. This straightforward method for phosphorene production does not involve the use of any surfactant or ultrasonication steps and is expected to facilitate future development of phosphorene research.…”

methods suffer from several limitations. Even though many efforts focused on the synthesis of BP derivatives have been reported, [10] research into the synthesis, properties, and applications of BP derivatives is still at an early stage, and a lot remains to be investigated.Although this research field is only a few years old, BP derivatives have already been utilized in a wide range of device applications such as transistors, batteries, supercapacitors, and solar cells. [20][21][22][23] These recent advancements highlight the potential importance of these exciting materials. In particular, based on recent theoretical and experimental studies, BP derivatives have shown great promise in enhancing the performance and lowering the cost of emerging photovoltaics (PVs). Considering the rapid advances of this cutting-edge research area, highlighting these discoveries and findings of the past few years is of great importance.Herein, we focus on providing a concise overview and timely update on the synthesis of BP derivatives and their recent applications in emerging solar cells including organic PV (OPV), dye-sensitized solar cells (DSSCs), heterojunction solar cells (HJSCs), and perovskite solar cells (PSCs).

“…[27][28][29][30][31][32] Recently, binary metal-free heterostructures combining BP and CN have shown promise in photocatalytic H 2 evolution and reactive oxygen species generation. [2][3][4][5][6][7][8][9][10][11] Owing to the unique optical and electrical properties, BP holds large promise in the fields of energy and catalysis. The preparation of these materials relies on the growth and exfoliation of BP crystals and the production cost and complexity increase inevitably.…”

An efficient metal‐free photocatalyst composed of black phosphorus (BP) and graphitic carbon nitride (CN) is prepared on a large scale by ball milling. Using economical urea and red phosphorus (RP) as the raw materials, the estimated materials cost of BP/CN is 0.235 Euro per gram. The BP/CN heterostructure shows efficient charge separation and possesses abundant active sites, giving rise to excellent photocatalytic H2 evolution and rhodamine B (RhB) degradation efficiency. Without using a co‐catalyst, the metal‐free BP/CN emits H2 consistently at a rate as large as 786 µmol h−1 g−1 and RhB is decomposed in merely 25 min during visible‐light irradiation. The corresponding electron/hole transfer and catalytic mechanisms are analyzed and described. The efficient metal‐free catalyst is promising in visible‐light photocatalysis and the simple ball‐milling synthetic method can be readily scaled up.
