Summary: The sol-gel spin coating technique was used to grow pure and Sr-doped SnO2 thin films on a glass substrate. The films exhibited a polycrystalline tetragonal crystal structure. Surface topography and roughness were analyzed with AFM. FTIR study showed the presence of various vibration peaks related to Sn-O, Sn-O-Sn, Sn-OH, and O-H. XPS spectra confirmed the presence of Sn, O, and Sr elements and their oxidation states in Sr-doped SnO2 films. Optical transmittance above 76% was achieved in the visible region, and the band gap energy decreased with Sr doping. Photoluminescence analysis revealed oxygen vacancies and emissions in green, UV, and blue regions. A low sheet resistance and high figure of merit were observed in a 3 at% Sr:SnO2 film.

Summary: Engineering the spectral lineshape of plasmonic modes through various electromagnetic couplings and mode interferences can significantly improve plasmonic sensing. A new approach is proposed to overcome the trade-off between bulk and surface sensitivities by combining near-field and far-field coupling in an intercalated 3-disk plasmonic crystal, achieving higher figure of merit and surface sensitivity. The design simplicity and high figure of merit highlight the potential of the 3-disk structure for a robust plasmonic sensing platform.

Summary: The Seebeck effect relates temperature gradient to electric voltage drop, with the Seebeck coefficient usually varying with temperature. Abnormal non-monotonic temperature dependence of the Seebeck coefficient in doped conducting polymers can be explained by contributions from multiple bands. Research shows that a small bandgap accessible for thermal activation between bands and a significant difference in bandwidth between the polaronic band and the conduction band (or valence band) can lead to the abnormal behavior of the Seebeck coefficient.

Summary: Anand et al. introduce an implicit equation for transparent conductive electrode (TCE) merit in photovoltaics by lumping series resistance in with the diode. However, an explicit equation has been previously derived by lumping series resistance external to the diode. While the choice of where to lump series resistance does not affect merit for TCEs of practical interest for PV, external lumping is preferred. Monolith deadspace, metal grid shadowing, and grid resistance shift TCE merit away from the figure of merit behavior published by Anand et al.

Summary: This study investigates the electrical, structural, and optical properties of La-doped SrSnO3 thin films with varying thickness. It is found that with increasing film thickness, vertical grain boundaries are formed and the orthorhombic phase is reoriented. The analysis of optical transmittance shows that La-doped SrSnO3 thin films have a high figure of merit in the deep-UV region.

Summary: This study reported the electrical conductivity and Seebeck coefficients of composite thin films containing different lengths of Ag2Te nanowires combined with a polymer. The results showed that films made from the longest nanowires exhibited higher electrical conductivity, and the length of the nanowires significantly affected the thermoelectric performance of the composite thin films.

Summary: Developing growth schemes for functional 2D nanomaterials, such as Bi2Se3 nanoplatelets, can be achieved through controlled colloidal synthesis based on oriented attachment, enabling facile doping without noticeable intercalation. The variation in optical properties confirms the higher concentration of charge carriers at the edge of structures, attributed to Se deficiency and low crystallinity, offering new possibilities for tuning the composition and thickness of nanostructured 2D Bi2Se3.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
