Summary: The study compares the physicochemical, optical, electrical, and photodetective properties of earth-abundant quaternary Cu2FeSnS4 (CFTS) nanoparticle-based films synthesized via different methods. It is found that the synthesis process significantly impacts the morphology, chemical composition, optical properties, electrical properties, and performance of CFTS nanoparticle-based visible photodetectors. Hydrothermal-synthesized CFTS nanoparticle-based detectors exhibit photoinactive properties, while solvothermal-synthesized devices have higher photosensitivity.

Summary: Poly(3-hexylthiophene) (P3HT) was synthesized by chemical oxidative polymerization using ferric chloride (FeCl3) as the oxidizing agent and various surfactants as shape templates. The effects of mole ratios, polymerization times, and surfactant types and concentrations on the electrical conductivity and particle properties were investigated. The results showed that P3HT synthesized with dodecylbenzenesulfonic acid (DBSA) at Critical Micelle Concentration (CMC) 6 had the highest electrical conductivity and particle size of 1530 +/- 227 nm. The thermal analysis revealed that surfactant-synthesized P3HT had higher stability and char yields. The electrical conductivity of DBSA-synthesized P3HT was further enhanced by doping with HClO4.

Summary: 3D printing technologies combined with chemical vapor deposition can be used to fabricate new hybrid materials with tunable properties. The thickness and crystallinity of graphene-based coatings can be controlled by altering the parameters of chemical vapor deposition. Transmission electron microscopy confirms the successful growth of nanocrystalline graphene layers on 3D printed α-Al2O3 substrates, resulting in fully-connected and highly conductive pathways. In terms of thermal conductivity, specimens decorated with graphitic coatings exhibit higher thermal conductivity compared to bare ceramic scaffolds.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
