Abstract
Tellurene has a phosphorene-like puckered configuration and exhibits great air stability. This characteristic makes it highly sensitive to some gases, and therefore, it has a huge potential in gas sensing applications. In this paper, the sensing performance of tellurene-based gas sensors toward SF6 decomposition products, including H2S, SO2, SO2F2, and SOF2, was systematically investigated. Three types of tellurene-based gas sensors were fabricated: single tellurene flake with ohmic contact (RCTF sensor), single tellurene flake with nonohmic contact (DCTF sensor), and drop-cast tellurene flakes with heat function (HTF sensor). The RCTF sensor exhibited good sensitivity and selectivity toward hydrogen sulfide but slow recovery speed like most two-dimensional materials. The DCTF sensor exhibited a significant improvement in sensitivity, selectivity, and recovery speed compared with the RCTF sensor. Finally, the HTF sensor demonstrated the fastest recovery speed of all tellurene-based sensors. This work showed that the nonohmic contact and heat pulse are easy and efficient methods to enhance the performance of tellurene-based gas sensors toward hydrogen sulfide, which supports the application potential of tellurene in gas sensors.

Abstract HfSe2 monolayer with high electron mobility and chemical activity is a good candidate for gas sensing application. Pd-doping with high catalytic performance would effectively enhance the adsorbing and sensing behaviors of HfSe2 monolayer upon target gas molecules. In this work, we using first-principles theory investigated the adsorption performance of intrinsic and Pd-doped HfSe2 (Pd-HfSe2) monolayer upon two toxic gases (NO2 and SO2), to explore their possible application as gas senso...

Abstract To give a first insight into the transition metal (TM) doped C3N monolayer for application of chemical gas sensors, we using first-principles theory in this paper investigated the adsorption performance of Ni-doped C3N (Ni-C3N) monolayer upon three SF6 decomposed species, including SO2, SOF2, and SO2F2. We first analyzed the stability of Ni-doping on the C3N monolayer where two sites were considered, namely the N-vacancy and C-vacancy site. It is found that N-vacancy would be the prefer...

Abstract: Two-dimensional (2D) semiconductors have been extensively explored as a new class of materials with great potential. In particular, black phosphorus (BP) has been considered to be a strong candidate for applications such as high-performance infrared photodetectors. However, the scalability of BP thin film is still a challenge, and its poor stability in the air has hampered the progress of the commercialization of BP devices. Herein, we report the use of hydrothermal-synthesized and air...

The field of chemical (gas) sensing has witnessed an unprecedented increase in device sensitivity with single molecule detection now becoming a reality. In contrast to this, the ability to distinguish or discriminate between gas species, has lagged behind. This is problematic and results in a high rate of false alarms. Here, we demonstrate a short period sinusoidal thermal modulation strategy to quantitatively and rapidly identify two industrially relevant gases (hydrogen sulfide (H2S) and sulfu...

There is an emerging need for semiconductors that can be processed at near ambient temperature with high mobility and device performance. Although multiple n-type options have been identified, the development of their p-type counterparts remains limited. Here, we report the realization of tellurium thin films through thermal evaporation at cryogenic temperatures for fabrication of high-performance wafer-scale p-type field-effect transistors. We achieve an effective hole mobility of ~35鈥塩m2鈥塚鈭1鈥塻...

Two-dimensional thin tellurene (Te) was effectively synthesized by a one-pot hydrothermal reduction process. It had the hexagonal phase with good crystallization, the extent of radiation absorption (400-850鈥塶m), and a 1.37鈥塭V band gap. Based on the evolution of the crystal structure and morphology, the formation mechanism of Te nanomaterials has been speculated by the time-dependent reactions as the nucleation of nanosized clusters first, then self-assembly into uniform nanowires, and, finally, ...

Chemiresistive sensor devices using two-dimensional (2D) materials have been extensively studied. However, so far no single material has all the desirable attributes. For example, graphene and MXenes lack a band gap, transition metal dichalcogenides (such as MoS2) lack high sensitivity, while phosphorene exhibits poor air-stability. Here we report that tellurene, a new emergent single-element 2D material, excels as a sensor for NO2 detection. Devices based on tellurene exhibit a detection limit ...

In this paper, the adsorption of four types of SF6 decomposed products over the perfect and defective (containing one S or W vacancy) WS2 monolayer was theoretically investigated using the density functional theory (DFT). By calculating the adsorption energy, electron transfer, and comparing the band structure and the density of states (DOSs) before and after gas adsorption, the physical and chemical interactions can be evaluated. The results show that the adsorptions of the gas molecule over th...

C5F10O (C5 perfluorinatedketone) has received extensive attention due to its great insulation and eco-friendly performance, which has the potential to replace SF6 usage in power industries. In this paper, the power鈥揻requency breakdown properties and discharge decomposition characteristics of C5F10O/Air and C5F10O/N2 gas mixtures are explored. It is found that the AC breakdown voltage of the C5F10O gas mixtures increases gradually with both the gas pressure and the content of C5F10O. As the parti...

Abstract null null The intrinsic and electronic properties of elemental two-dimensional (2D) materials beyond graphene are first introduced in this review. Then the studies concerning the application of gas sensing using these 2D materials are comprehensively reviewed. On the whole, the carbon-, nitrogen-, and sulfur-based gases could be effectively detected by using most of them. For the sensing of organic vapors, the borophene, phosphorene, and arsenene may perform it well. Moreover, the G-ser...

Tellurium (Te) is a novel elementary material, which has recently attracted extensive attention due to its intriguing physical properties, such as topological, thermoelectric, and photoelectric properties. Further study on Te crystal structures will help to understand its properties and facilitate its application. Here, the angle-resolved polarized Raman spectroscopy has been employed to study Te crystal symmetry. Three different Raman vibration modes were obtained, each of which possess a diffe...

Sulfuryl fluoride (SO2F2) is one of the ideal decomposition components of sulfur hexafluoride (SF6), which has been widely used as insulating and arc-quenching medium in gas-insulated switchgear (GIS) power equipment. To detect SF6 decomposition component at room temperature, use of SO2F2 still poses challenges. In this work, we have successfully prepared TiO2 nanofibers and Nickle sulfate (NiSO4 NPs) via facile electrospun and hydrothermal methods, followed by calcination process to improve sen...
