Summary: This study investigates the structural, electrical, and optical properties of recently synthesized pyrrolo[1,2-i][1,7] phenanthrolines derivatives in thin films. The films were deposited on glass substrates using a spin coating technique and chloroform as a solvent. The results show that the thin films exhibit a polycrystalline structure with n-type semiconductor behavior after heat treatment. The thermal activation energy ranges from 0.68 to 0.78 eV, and the direct optical band gap values are between 4.17-4.24 eV. The electrical and optical properties are discussed in relation to the microstructural properties determined by the molecular structure. These organic compounds show promise for applications in organic optoelectronics and nanoelectronics.

Summary: This work demonstrates successful epitaxial thin film growth of semiconducting chalcogenide perovskite alloys in the Ba-Zr-S-Se system using gas-source molecular beam epitaxy (MBE). The resulting films are environmentally stable and have a tunable direct band gap (E-g) from 1.9 to 1.5 eV, depending on the Se content. This opens up possibilities for various optoelectronics applications such as visible and near-infrared (VIS-NIR) devices, solid-state lighting, and solar cells using chalcogenide perovskites.

Summary: This study investigated the structures of two Se chains confined inside single-walled carbon nanotubes (SWCNTs), revealing that the chains were linear and parallel. The covalent bond between Se and SWCNT was found to be stronger than that between Se and trigonal Se (t-Se). The interaction between chains was attributed to the overlap of electronic orbitals, and the disappearance of this overlap in the encapsulated Se chains enhanced the covalent bonds.

Summary: In this study, we elucidate the hopping mechanism of hydrogen at intermediate temperature using a combination of experimental data and theoretical calculations. We find that the transition from thermal hopping to quantum tunneling is attributed to resonant tunneling, which is achieved through the resonant tunneling of discrete vibrational states between the edge octahedral site and the tetrahedral site. We also demonstrate that the tunneling rate can be tuned by energy level matching.

Summary: Fe-based nanowires containing nonmagnetic elements, fabricated using a pulse electrodeposition method in porous anodic alumina membranes, exhibit magnetic tunability. The magnetic properties of Fe100-xSnx NW arrays, with a diameter of about 35 nm, such as coercivity and squareness values, decrease with increasing Sn content. The structure of the FeSn NWs, dominated by Fe or FeSn alloy crystal phase, can be either single domain or pseudo-single domain states depending on the Sn content.
