Summary: This report investigates the room temperature magnetodielectric effect of polycrystalline BiFe0.8Mn0.2O3 ceramics. Mn-doping results in weak ferromagnetic response due to changes in the spiral spin ordering. Bi vacancies cause charge compensating oxidation of Mn3+/Mn4+, leading to weaker ferromagnetic properties.

Summary: Electro-optic thin film materials play a crucial role in the fabrication of optical modulators in integrated photonic circuits and it is important to develop strategies to tune the linear electro-optic effect. Strain engineering has emerged as a powerful tool for optimizing the electro-optic coefficients in ferroelectric thin films. This study investigates the electro-optical properties of polycrystalline bismuth ferrite (BiFeO3) thin films and characterizes their electro-optic coefficients under different substrate-induced thermal stress.

Summary: In this study, p-NiO/Al Schottky barrier diodes were fabricated and characterized using dc reactive magnetron sputtering. The effect of post-annealing temperature was investigated. Various characterization techniques were used to analyze the physical properties of the NiO thin films. The metal-semiconductor interface behavior was studied using current-voltage characterization and the Thermionic emission and Chueng model. The results showed a rectification ratio of 10(3) at +/- 3 V and the barrier height varied with annealed treatment. The electrical characteristics of the Schottky device were evaluated using ac measurements.

Summary: This study demonstrates the three-state resistive switching (RS) phenomenon on a Pt/BiFeO3/SrRuO3 structure. The three-state storage capability is attributed to the movement of oxygen vacancies and the trapping/detrapping of charge carriers at the interface. Additionally, a ternary OR logic gate is designed using only one memristor.

Summary: Ce-doped indium oxide (ICO) films were prepared via reactive plasma deposition, and the impact of annealing temperature and time on the electrical, optical, and structural properties of the films was investigated. The results showed that annealing treatment improved the crystallinity, grain size, transmittance, and reduced resistivity of the ICO films. Annealing at 210 degrees C in air for 50 min yielded films with a mobility of 93.3 cm²/V s, carrier concentration of 2.48 x 10²⁰/cm³, average transmittance of 86.5%, and resistivity of 2.6 x 10⁻⁴ Ω·cm. The ICO films exhibited higher carrier mobility and lower carrier concentration compared to Sn-doped In₂O₃ (ITO) films, which is favorable for enhancing the efficiency of solar cells.

Summary: This study investigates the influence of the polarity of polymer matrices on persistent room-temperature phosphorescence (pRTP). It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

Summary: In this study, a new spin-gapless semiconductor material CoFeMnSn is reported, and its stable structure and spin-polarized band structure are determined through experimental realization and theoretical calculations. The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
