“…In addition, SnS 2 can be easily oxidized to SnO x at temperatures above 160 °C, which makes gas sensor vulnerable to issues of long-term stability; [37] Figure S4 in the Supporting Information shows more details about the temperature dependency of this gas response. The response of this SnS 2 gas sensing device to NO 2 was monitored Small 2018, 14,1704116 at 3-100 ppm as shown in Figure 4b. Adsorption of NO 2 molecules to the surface of the SnS 2 nanosheets causes an increase in resistance, since NO 2 is a well-known electron acceptor and SnS 2 is an n-type semiconductor with electrons as a major carrier (see Figure S3, Supporting Information).…”

2D layered materials with sensitive surfaces are promising materials for use in chemical sensing devices, owing to their extremely large surface-to-volume ratios. However, most chemical sensors based on 2D materials are used in the form of laterally defined active channels, in which the active area is limited to the actual device dimensions. Therefore, a novel approach for fabricating self-formed active-channel devices is proposed based on 2D semiconductor materials with very large surface areas, and their potential gas sensing ability is examined. First, the vertical growth phenomenon of SnS nanocrystals is investigated with large surface area via metal-assisted growth using prepatterned metal electrodes, and then self-formed active-channel devices are suggested without additional pattering through the selective synthesis of SnS nanosheets on prepatterned metal electrodes. The self-formed active-channel device exhibits extremely high response values (>2000% at 10 ppm) for NO along with excellent NO selectivity. Moreover, the NO gas response of the gas sensing device with vertically self-formed SnS nanosheets is more than two orders of magnitude higher than that of a similar exfoliated SnS -based device. These results indicate that the facile device fabrication method would be applicable to various systems in which surface area plays an important role.

Conducting polymers have shown appealing performances as sensing materials in various smart sensors such as gas, chemical and biological sensors, owing to their unique physical and electrical properties. This study reports a novel development for the fabrication of visual-aided smart thermal (VAST) sensors. The sensors are based on conducting polymers, temperaturesensitive resin, and liquid crystal molecules via direct scrawling and in situ solventless polymerization. In the VAST sensor, the thermochromism resins and liquid crystals form a visual-aided system with the real-time early warning function and the conducting polymers provide an ultrahigh resolution by the measure of the change of resistivity. Additionally, these VAST sensors also hold the advantages of low cost, using simple tools, high stability, excellent adaptability to arbitrary substrates, wide application fields, and facile largescale fabrication. These properties are in favor of fabricating smart thermal sensors to satisfy the practical demands, such as the demonstrated temperature detecting system (especially flexible devices with nonplanar surface), thermodefect diagnostic system, smart battery monitoring system, and other environment monitoring.

Layered transition‐metal dichalcogenides (TMDs) have recently attracted intense scientific and engineering interest because of their unique semiconducting and opto‐electronic properties. We investigated the pressure‐induced structural phase transition of layered semiconductor molybdenum disulfide (MoS2) using Raman spectroscopy and studied its metallization using infrared (IR) spectroscopy under both non‐hydrostatic and quasi‐hydrostatic conditions. Under quasi‐hydrostatic and non‐hydrostatic conditions, we found that the structural phase transition from 2Hc stacking to 2Ha stacking starts at approximately 16 and 21 GPa, respectively, and finishes at ∼35 and ∼41 GPa, respectively. Furthermore, the structural phase transition was followed by a semiconductor‐to‐metal (S‐M) electronic transition. The pressure point of metallization under quasi‐hydrostatic conditions is ∼5 GPa lower than that under non‐hydrostatic conditions.
