“…From a microstructural point of view, Fe(Se,Te) film shows in both cases a clear Kikuchi pattern (insets of figures 4(a) and (b)), corresponding to the superconducting tetragonal phase [34]. Also EBKPs confirm that Fe(Se,Te) film is rotated in plane by 45 • .…”

The epitaxial growth of Zr-doped CeO 2 (CZO) films by chemical solution deposition (CSD) on single crystal substrates such as Al 2 O 3 , SrTiO 3 and Y 2 O 3 -stabilized ZrO 2 (YSZ) and their use as buffer layers for Fe(Se,Te) film growth are reported. The growth of 30 nm thin CZO films is mostly dominated by dewetting issues, leading to highly incomplete substrate coverage due to the strong tendency of CZO grains to agglomerate. This effect is less severe on YSZ substrate and, in addition, can be fully controlled by setting the deposition temperature at 950 • C and operating under Ar-H 2 reducing atmosphere. These conditions promote the growth of epitaxial and compact CZO films on YSZ, showing a flat surface morphology with root-mean-square roughness around 2.5 nm. Preliminary results on Fe(Se,Te) film deposited by pulsed laser deposition on CZO-buffered YSZ are reported. Although good epitaxial growth is achieved on CZO buffer layer, Fe(Se,Te) films exhibit poor superconducting properties. On the other hand, Fe(Se,Te) films show excellent properties when a seed layer is used, exhibiting a sharp superconducting transition at about 17 K and a critical current density exceeding 1 MA cm −2 at 4.2 K in self field. The main role of the seed layer, consisting of a non-superconducting Fe(Se,Te) film, is to favour the crystal and chemical matching between buffer layer and film, allowing for the growth of high-quality superconducting Fe(Se,Te) at deposition temperature as low as 200 • C.In perspective of applications, this result is a significant step towards process simplification and cost reduction of Fe(Se,Te)-based coated conductor technology development, being the first demonstration of superconducting Fe(Se,Te) films grown on CSD buffer layer.

“…A few more chalcogenides and related materials have also been successfully synthesized by the MSS strategy, such as Fe(Se 0.5 Te 0.5 ) solid pellet, 1D zinc selenophosphates, sulfur-doped silicon, La 3 Fe 0.5 GeSe 7 , La 3 MnGaSe 7 , Ce 3 Fe 0.5 SiSe 7 , Ce 3 Mn 0.5 SiSe 7 , Sm 3 Fe 0.5 SiSe 7 , Sm 3 Mn 0.5 GeSe 7 , Cu 10 Cd 2 Sb 4 S 13 , etc. − The MSS has also been employed to prepare chalocogenide-related heterojunctions. For example, Zhong et al synthesized TiO 2 NP@MoS 2 nanosheet heterojunction using the MSS strategy (Figure d–f) .…”

Recent Developments on Molten Salt Synthesis of Inorganic Nanomaterials: A Review

A wide range of inorganic nanomaterials with many fascinating properties and application potentials in widespread fields may be synthesized by wet chemical synthetic routes. To achieve scientific and commercial viability of nanomaterials with uniformity and scalability, it is necessary to develop efficient and cost-effective, preferably sustainable, methods. The molten salt synthesis (MSS) method is one such bottom-up technique to fabricate a wide variety of inorganic nanomaterials with tunable size, morphology, and surface characteristics. It is also environmentally friendly, cost-effective, simple to operate, easy to scale, and generalizable, etc. This review gives a critical overview on this emerging and rapidly developing method for making defect free nanomaterials in well-defined texture, surface, and morphology at a relatively low formation temperature. We have discussed its different aspects, including the role of molten salts, the choice of molten salts, the electrochemical aspects, some advanced modifications of the conventional MSS technique, and their implications. To show the most recent development on MSS synthesized inorganic nanomaterials, this review only encompasses the studies reported over the last six years (2015−2020). We have summarized technologically important and emerging families of inorganic nanomaterials such as metal oxides, fluorides, nitrides, silicides, chalcogenides, oxohalides, borides, and carbides. Finally, a few perspectives for the MSS method are highlighted. It is expected that this review will further attract scientists to explore the MSS method in making size-and shape-tunable nanomaterials.
