“…Hydrothermal synthesis of particles of PbSe smaller than 50 nm has also been reported [105]. Biswas et al have reported the hydrothermal synthesis of a-MnS nanocrystallites with rock salt structure using a non-aqueous solvent [106]. The crystals are well-faceted, pyramid-like single crystals of a-MnS.…”

“…Weak peaks at diffraction angle 2h = 21.4°and 37.4°can be attributed to X-ray flux and impurities due to sample handling or adsorbed dirts. Some authors have described emergence of MnO x and Mn(OH) 2 as possible intermediate impurities at temperature of about 200°C during hydrothermal production of MnS [5,6]. In this study, sample growth was carried out at room temperature and there was no expectation of any intermediate impurity.…”

“…In this study, sample growth was carried out at room temperature and there was no expectation of any intermediate impurity. Absence of peaks attributable to meta-stable phase indicates that annealing temperature supplied enough activation energy to successfully transform thermodynamically unstable MnS phase to stable rock salt structure (aphase) [3,5]. Using Debye Scherer's formula stated in Eq.…”

Stable α-MnS thin film deposited by two-electrode cell: synthesis, structural characterization and photoemission spectroscopic studies

Stable MnS thin film was deposited from catalyst-free inorganic solution by electrochemical cell. The film was characterized by some surface profiling techniques. Morphology revealed that film's particles were fairly distributed across substrate's surface. Crystallinity and surface growth height/roughness were observed before and after post-deposition annealing. Optical studies further showed that annealing has improved film transmittance across visible wavelength region. Reflections from planes associated with only rock salt structure of MnS were prominently identified by diffraction studies. An estimated average crystal size of 17.40 nm suggested that the deposited film is mainly composed of nanocrystalline particles. Film durability was appraised by core-level profiling of Mn and S binding energy (BE) positions during X-ray photoemission spectroscopy (XPS). The results indicated that before and after vacuum annealing, chemical states of Mn and S remained the same suggesting that the film did not undergo any form of transformation after long exposure to ambient environment. This study demonstrated sustainability of MnS electrode in extreme environmental condition.

Abstract2D materials have exceptional physical and chemical characteristics, which makes them attractive for wearable technology. These characteristics include high carrier mobility, outstanding mechanical performance, abundant chemistry, and excellent electrostatic tunability. However, due to the high electron doping effect of interfacial charge impurities and intrinsic defects, most reported 2D materials are n‐type. Complementary electronic devices and high‐performance wearable sensors necessitate the development of p‐type 2D semiconductors, which have superior electrocatalytic performance in oxidative processes compared to their n‐type counterparts. This review paper thoroughly accounts for recent advancements in 2D p‐type semiconductor‐based wearable sensors, covering basic understandings, synthesis and fabrication, functional devices, and sensor performance insights. Finally, challenges and future opportunities for 2D p‐type semiconductor‐based wearable sensors are discussed.
