We describe a new thin film deposition method for the growth of crystalline SbSI micro-needles via the conversion of Sb2S3 using SbI3 vapour, in a facile process that takes less than 15 minutes.

The use of Prussian blue analogues (PBA) materials in electrochemical energy storage and harvesting has gained much interest, necessitating the further clarification of their electrochemical characteristics. However, there is no well-defined technique for manufacturing PBA-based microelectrochemical devices because the PBA film deposition method has not been well studied. In this study, we developed the following deposition method for growing copper hexacyanoferrate (CuHCFe) thin film: copper thin film is immersed into a potassium hexacyanoferrate solution, following which the redox reaction induces the spontaneous deposition of CuHCFe thin film on the copper thin film. The film grown via this method showed compatibility with conventional photolithography processes, and the micropattern of the CuHCFe thin film was successfully defined by a lift-off process. A microelectrochemical device based on the CuHCFe thin film was fabricated via micropatterning, and the sodium ion diffusivity in CuHCFe was measured. The presented thin film deposition method can deposit PBAs on any surface, including insulating substrates, and it can extend the utilization of PBA thin films to various applications.

An amorphous quaternary Ba-Sr-Co-Fe (a-BSCF) oxide film was fabricated by a simple and scalable photochemical thin-film deposition method. a-BSCF demonstrates superior electrocatalytic activity towards the oxygen evolution reaction in 0.1 M KOH solution.

ABSTRACTNanostructured materials are being extensively studied because their ∼1–100nm grain size can dramatically affect properties. Most nanocrystalline synthesis methods produce particulate or flake. The process of consolidation also allows coarsening, contamination, and the introduction of porosity. The effect of nanocrystallinity on mechanical properties must be deconvoluted from these extrinsic artifacts. Most synthesis routes also produce small quantities of material. Reproducibly making enough specimens to explore more than a few properties is thus difficult. This paper describes thin-film processes to produce nanostructured materials. Thin-film deposition can easily produce many specimens, free from extrinsic artifacts, with identical composition and processing history. Many methods are now well established to study a variety of thin-film mechanical properties. We show examples of nanostructured films generated by controlling deposition and/or post-deposition processing.
