“…The sensor also showed good stability for up to 1000 bending cycles, making it suitable for wearable electronics. Although borophene-based sensor shows a strong response to NO 2 the sensitivity is still lower than carbon nanomaterials and polymer composites [ 104 ]. Another research, conducted by the same group, demonstrated the graphene-borophene heterostructure for humidity sensing.…”

Quantum flatland i.e., the family of two dimensional (2D) quantum materials has become increscent and has already encompassed elemental atomic sheets (Xenes), 2D transition metal dichalcogenides (TMDCs), 2D metal nitrides/carbides/carbonitrides (MXenes), 2D metal oxides, 2D metal phosphides, 2D metal halides, 2D mixed oxides, etc. and still new members are being explored. Owing to the occurrence of various structural phases of each 2D material and each exhibiting a unique electronic structure; bestows distinct physical and chemical properties. In the early years, world record electronic mobility and fractional quantum Hall effect of graphene attracted attention. Thanks to excellent electronic mobility, and extreme sensitivity of their electronic structures towards the adjacent environment, 2D materials have been employed as various ultrafast precision sensors such as gas/fire/light/strain sensors and in trace-level molecular detectors and disease diagnosis. 2D materials, their doped versions, and their hetero layers and hybrids have been successfully employed in electronic/photonic/optoelectronic/spintronic and straintronic chips. In recent times, quantum behavior such as the existence of a superconducting phase in moiré hetero layers, the feasibility of hyperbolic photonic metamaterials, mechanical metamaterials with negative Poisson ratio, and potential usage in second/third harmonic generation and electromagnetic shields, etc. have raised the expectations further. High surface area, excellent young’s moduli, and anchoring/coupling capability bolster hopes for their usage as nanofillers in polymers, glass, and soft metals. Even though lab-scale demonstrations have been showcased, large-scale applications such as solar cells, LEDs, flat panel displays, hybrid energy storage, catalysis (including water splitting and CO2 reduction), etc. will catch up. While new members of the flatland family will be invented, new methods of large-scale synthesis of defect-free crystals will be explored and novel applications will emerge, it is expected. Achieving a high level of in-plane doping in 2D materials without adding defects is a challenge to work on. Development of understanding of inter-layer coupling and its effects on electron injection/excited state electron transfer at the 2D-2D interfaces will lead to future generation heterolayer devices and sensors.

“…Recently, first-principles calculations have successfully demonstrated borophene as a promising material for gas sensing applications, specifically for NO 2 gas. 102 It was noticed that the borophene-based chemiresistive sensor exhibited a wider linear range from 200 ppb to 100 ppm, offering several analytical merits such as lower detection limit (200 ppb), rapid response (30 s), and good recovery (200 s) at room temperature. The developed borophene-based sensor exhibited flexibility, stability and selectivity for the sensing of NO 2 gas (Fig.…”

“…[1][2][3][4][5][6][7][8] These properties make borophene one of the most promising 2D materials for various applications ranging from high-efficiency energy conversion and storage devices, sensors, and detectors to next-generation quantum devices. 2,[9][10][11] It is theoretically predicted that the structural stabilities of borophene depend on the hexagon vacancy concentration on various metal substrates in the range of 1/6-1/ 9, such as honeycomb and triangular borophene and d 6 , a, b 12 and c 3 boron sheets. 3,12 Based on these predictions, borophenes with various phases have been successfully grown on typical metal substrates such as Ag and Cu via molecular beam epitaxy under ultrahigh vacuum conditions and synthesized by the chemical vapor deposition (CVD) method.…”
