“…Fig. 9 shows the X-ray absorption spectroscopy (XAS) spectra of the SnO film grown on an yttriumdoped ZrO 2 (YSZ) (001) substrate, reproduced from those reported previously (McLeod et al, 2012;Quackenbush et al, 2013;Sharma et al, 2016;Minohara et al, 2019). To investigate the compositional homogeneity, the SX was set to be the photon energy corresponding to the characteristic/intense absorbed peak structure near the Sn M-edge (487.6 eV) and O K-edge (534.2 eV), and the spatial distribution was measured.…”

A high-precision XYZ translator was developed for the microanalysis of electronic structures and chemical compositions on material surfaces by electron spectroscopy techniques, such as photoelectron spectroscopy and absorption spectroscopy, utilizing the vacuum ultraviolet and soft X-ray synchrotron radiation at an undulator beamline BL-13B at the Photon Factory. Using the high-precision translator, the profile and size of the undulator beam were estimated. They were found to strongly depend on the photon energy but were less affected by the polarization direction. To demonstrate the microscopic measurement capability of an experimental apparatus incorporating a high-precision XYZ translator, the homogeneities of an SnO film and a naturally grown anatase TiO2 single crystal were investigated using X-ray absorption and photoemission spectroscopies. The upgraded system can be used for elemental analyses and electronic structure studies at a spatial resolution in the order of the beam size.

“…186 Very recently, also SnO x /Au/SnO x multi-layers have been reported with R sh ¼ 52 U sq À1 and a transmittance of 83% for l > 475 nm. 187 Behrendt et al used SnO x prepared by atomic layer deposition (ALD) to sandwich ultra-thin Ag or Cu layers (thickness 7 nm). A sheet resistance of 9 U sq À1 and 20 U sq À1 has been achieved for the Ag and Cu based sandwich electrodes, respectively (Fig.…”

“…The bare metal mesh (Au‐Ag) from Hamelia leaf template shows 80% transmittance in the visible resign and the transmittance enhances up to 84% when mesh structure is embedded into the SnO 2 layers (Figure S6, Supporting Information). Our previous investigations also suggest that transition metal oxides are best materials for such structures …”

“…After silver deposition, the Ag vein structure was heated beneath to remove the vein part of the specimen. No peak is seen for SnO 2 showing amorphous behavior which is due to deposition being done at room temperature . Amorphous behavior will also support the flexibility of the hybrid multilayer structure.…”

etc. Macroscopic metal grids have been successfully developed and used as a front electrode for inorganic solar cells and are a potential replacement of thin metal films as transparent electrode (TE) in organic optoelectronic devices also. [19] They exhibit high visible light transparency due to the large open area between the thick lines of metals and high conductivity due to the continuity of mesh with metal lines crossing each other and reduced junction resistance. Tuning of the work function is also possible by selecting the metal. [20] Photolithography, nanolithography, or transfer printing methods have been employed to develop metal grid electrodes, which however are complicated and tedious processes. [21,22] Metal nanowires-based 1D network shows the high merit of optical and electrical properties on becoming an excellent transparent conducting electrode, but suffer from certain limitations such as rough surface finish, poor adhesion properties, change in properties with temperature variation. The bare Ag NW suffers from oxidation and melting issues when exposed to temperature and air during device fabrication and application. The best possible solution is to cover such a structure with high refractive index n-type materials with high thermal stability. The metal oxide is a suitable candidate to combine with such nanostructures. Hybrid structures (dielectric/metal NW/dielectric, DMD) have been used to resolve these issues. [3] Here, metal governs the electrical while dielectric layer improves optical properties of the hybrid structure. [23] This conventional DMD structure possesses adequate transparency in the visible region. These DMD structures due to high transparency and sufficient conductivity show great promise for their potential use in next-generation optoelectronic and energy devices. [24] Metal mesh is preferred over nanowires/macrowires because of less contact and junction resistance. [25] There are few reports of fabrication of metal nanostructure using soft lithography [9] and leaf structure [25] for energy and optoelectronics applications. [26] However, an extensive investigation is needed to test the structural properties and stability over a wide temperature range of such structures.The present research work reports the fabrication and study of bioinspired metal grid electrode. The electrode exhibits better, 1D metal network is one of the promising alternatives of the conventional transparent conducting electrode (TCE) viz ITO/FTO. Bioinspired fabrication of junction resistance free metal grid structures is explored for their TCE applications. The leaf-based metal grid electrodes exhibit low DC resistivity (10 −5 -10 −4 Ω cm) and high optical transparency (80-90%) in the visible spectrum. The leaf vein structures are varied to obtain better optoelectronic properties. Finally, a multilayered stacked structure (SnO 2 -Ag-Au-SnO 2 ) is deposited on a poly ethyl terephthalate substrate and low-to high-temperature electrical stability is demonstrated. X-ray photoelectron spectroscopy results are...
