“…The response of the SnS 2 sensor toward NO 2 was very high compared to the other sensors discussed here as well as other TMDC and metal oxide based NO 2 sensors reported in literature (refs. [252,326] and references therein). However, although the response time was not studied in detail, it is apparent that the slow response of the ALD SnS 2 sensor as well as most of the other sensors discussed here needs to be improved in the future.…”

“…Most of the studies have focused on detection of NO 2 , a toxic gas emitted to the atmosphere from combustion of fossil fuels that is harmful even at levels below 1 ppm. [ 326 ] An important part of gas sensor studies is to examine cross‐sensitivity to other gases, which should ideally be low. In addition, useful gas sensors should respond and recover quickly during and after exposure to changes in atmosphere and should preferably be operated with only moderate heating or even at room temperature.…”

it was soon replaced by other materials. Research on the fundamental properties and preparation of TMDC monolayers in solution (1986), [8] on single-crystal substrates in ultrahigh vacuum (2001), [9] and in an accessible way using mechanical exfoliation [10] (2005) followed. It was the discovery of graphene in 2004 [11] with its ever expanding list of unique and exciting properties, phenomena, and potential applications [12] that amassed broad attention to 2D materials and resulted in the 2010 Nobel Prize in Physics awarded to Andre Geim and Konstantin Novoselov. Tremendous efforts have been put toward synthesis and applications of graphene, including the billion euro Graphene Flagship project funded by the European Union. [13,14] Graphene is a semimetal, however, and the need to have semiconducting materials for many crucial applications, in particular in electronics, has led researchers to search for other 2D materials. The scientific community turned to TMDCs following breakthroughs in observation of unique thickness-dependent properties, [15,16] monolayer synthesis using chemical vapor deposition (CVD), [17,18] and demonstration of high-performance semiconductor devices [19-21] in 2010-2013 (Figure 1). Indeed, in 2013 the number of scientific publications on TMDCs, in particular MoS 2 , nearly tripled over 2012, and the strong growth has continued to date, fueled by advances in synthesis, new devices, and exciting physical phenomena. The explosive growth in MoS 2 research has also expanded to other TMDCs, [22] resulting in yet new phenomena and potential applications being found. [23-26] It is now clear that TMDCs are remarkable in many ways. Their layered crystal structure gives rise to fundamental physics not seen in 3D materials, which enables novel devices and applications. [25,26,32,34-36] The layered structure also gives TMDCs their highly anisotropic properties, extremely high specific surface areas, possibility to intercalate different species between the layers, and stability as ultrathin sheets down to three atomic layers thick. The TMDC family contains dozens of different materials from semiconductors to semimetals, metals, and even superconductors. [5,22,25,34] However, TMDC research is still mostly in the early discovery stages and the investigations of TMDCs largely continue using flakes produced by mechanical exfoliation of bulk crystals. [10,26] Unfortunately, this method cannot be scaled up for practical 2D transition metal dichalcogenides (TMDCs) are among the most exciting materials of today. Their layered crystal structures result in unique and useful electronic, optical, catalytic, and quantum properties. To realize the technological potential of TMDCs, methods depositing uniform films of controlled thickness at low temperatures in a highly controllable, scalable, and repeatable manner are needed. Atomic layer deposition (ALD) is a chemical gas-phase thin film deposition method capable of meeting these challenges. In this review, the applications evaluated for ALD TMDCs are systematically...

A study of altering the conductive properties of wool fibers by applying copper selenide is presented. The researched modification of wool fibers was based on a two-stage adsorption-diffusion process. X-ray diffraction, scanning electron microscope, energy-dispersive X-ray spectrum, and Fourier transform infrared spectroscopy were performed to evaluate the morphological and physical characteristics of all CuxSe-coated wool fibers. X-ray diffraction (XRD) data showed a single, Cu0.87Se (klockmannite), crystalline phase present, while Atomic Absorption Spectroscopy (AAS) and Energy Dispersive X-ray (EDX) analyses showed that the concentrations of Cu and Se in copper selenide coatings depend on the number of wool fiber treatment cycles. It was determined that a dense layer of CuxSe grows through a nucleation mechanism followed by particle growth to fill out the complete surface. It was found that the conductivity of the coated wool fibers depends on the quality and density of the copper selenide coating, thus the resistance of electrically impermeable wool fibers can be reduced to 100 Ω by increasing the number of treatment cycles.

“…Among these 2D materials, TMDs caught a lot of concern in gas sensors because of its stable semiconducting property, high thermal stability, and appropriate carrier mobility [13][14][15]. For example, SnS 2 or MoS 2 could be used to sense NO 2 , WS 2 is an excellent candidate to be applied in a dissolved gas analyzer (DGA) [16][17][18].…”

Owing to their harmful and polluting the environment, nitrogen oxides and sulfur dioxide are expected to monitor when they are used. However, the widespread use of gas sensing methods presents obstacles in terms of portability or stability. Hence, a better detect way needs to be found urgently. The success of graphene-based gas sensors has stimulated interest in two-dimensional (2D) materials in the gas sensing area. Transition metal dichalcogenides (TMDs), such as MoS2 or WS2, are considered to have the high-performance potential for gas sensors. Unfortunately, when used as a gas sensor, the sensing response of the pristine TMDs is greatly affected by a number of gas molecules that are too weak to be detected. Herein, to evaluate the sensing capability of Al, P, and Fe-doped WS2 to NO, NO2, and SO2, the molecular model of the adsorption systems was constructed, and density functional theory (DFT) was used to calculate the adsorption behavior of these gases. The binding force of all the doped-WS2 to the harmful gas molecules is much stronger than that of the pristine WS2. According to the results of adsorption energy, band structure, and state density, Al-doped WS2 has the potential to be used as NO and SO2 gas sensor, while P-doped WS2 is selective to NO. This work opens up a new reference for choosing appropriate doping types on 2D materials for noxious gas sensing.
