The characterization of barium hexaferrite thin-films at microwave frequencies is important for determining their electromagnetic properties by measuring the elements of the permeability tensor. Layers of 15 μm were deposited by RF sputtering on a coplanar line. By measuring the S parameters under magnetic field conditions, the μ and κ elements of the permeability tensor were extracted and their variations as a function of the applied field were highlighted. Possible applications to absorbent layers are being considered

Anatase TiO2 nanosheets film with dominant (001) facets (TF-1) has attracted widespread research interest owing to wide-ranging industrial applications and fundamental importance. In this work, we prepared TF-1 with well adhesion on quartz substate in a short time (20 min) by radio frequency (RF) pulse-modulated plasma with hydrofluoric acid (HF) as the morphology controlling agent (MCA). Many intercrossed nanosheets were observed on the surface of TF-1 through SEM images, which provides more exposed reactive (001) facets. The degree of truncation (B/A) and the percentage of exposed (001) facets (S001/S) were estimated by XRD patterns and Raman spectra, which have been increased due to the presence of HF. XPS results indicate that F atoms are only adsorbed on anatase surface rather than doped into TiO2 lattice. The functions of HF on the growth of anatase TiO2 nanosheets were studied by density functional theory (DFT), revealing the stabilization effects associated with chemisorbed fluorine (F) atoms over (001) surface, and thus stimulating its preferred growth.

The citrate sol-gel process was used to produce Sr2FeO4 strontium ferrite powder. The method involves metallic nitrates, citric acid and distilled water as a solvent, followed by calcination. The Ruddlesden-Popper structure of the resulting compound was identified by XRD analysis. The different molecular structures and vibration bands were studied by FTIR. The morphology of the powder was analysed using SEM. Samples appear of good crystalline quality and with interesting nanostructure. We studied optical properties and determined the band gap energy to lie about 2.8 eV, Sr2FeO4 can thus absorb photons having a wavelength less than 444 nm, approximately, making this compound potentially interesting for applications.

This work presents a nitrogen dioxide (NO2) gas sensor based on porous silicon with improved sensitivity, selectivity, and cost-efficiency. Porous silicon is being researched as an alternative material for gas sensors operating at room temperature (RT), making it suited for low-consumption applications. Meso-porous silicon (meso-PS) films were prepared on p+ type Si (100) using an electrochemical method for NO2 gas sensing. Morphology, structural and optical properties of meso-PS films were investigated using scanning electron microscope (SEM), X-ray diffractometer (XRD), and UV-Vis spectroscopy. The gas sensing response of meso-PS samples was performed at RT with top parallel Al electrodes in the range of 4 to 10 ppm of NO2 gas. The tested sensor showed high normalized response (Rair/Rgas =40 for 4 ppm to 100 for 10 ppm) thanks to its high surface/volume ratio, good repeatability and reversibility, fast response (40 s) and recovery times (18 s), and good selectivity for NO2 vs. NH3, O3 and CO. All these performances obtained at RT are encouraging for low-power devices.

In our study, we aim to investigate the structural, electronic, and magnetic properties of CdVTe, a diluted magnetic semiconductor with a Cadmium telluride (CdTe) structure. To achieve this, we employ the full potential linear augmented plane wave method implemented in the CASTEP code, which allows us to accurately simulate the behavior of the system. To describe the electronic exchange and correlation effects, we adopt the generalized gradient approximation (GGA) within the density functional theory (DFT) framework. This choice of methodology ensures reliable and accurate calculations of the electronic and magnetic properties of Cd1-xVxTe. Our results reveal that the substitution of Vanadium (V) into the Cadmium (Cd) site of the CdTe lattice does not alter the zinc blende crystal structure, demonstrating the stability and structural integrity of the system. Furthermore, our calculations demonstrate that the introduction of Vanadium impurities leads to spin polarization within the material, resulting in the emergence of a magnetic moment. Notably, we find that a Vanadium concentration of approximately x≈0.12 exhibits the strongest magnetic properties, characterized by a significant magnetic moment. These findings provide valuable insights into the behavior and potential applications of CdVTe as a diluted magnetic semiconductor, shedding light on the interplay between structural, electronic, and magnetic properties in this material.

Rare earth sesquioxide (R2O3) have attracted significant attention because of their stable surface and operable optical properties. In this paper, we comprehensively analyze the surface and optical properties of five rare earth sesquioxides (R2O3, where R=Sc, Y, La, Sm, Dy) using the first-principles method. The obtained results are consistent with other theoretical and experimental values. It is observed that the R terminated surfaces of R2O3 exhibits the lowest work function while the mixed atom terminations have the lowest surface energy, indicating their potential as electron emission materials. Additionally, calculations of optical properties reveal that R2O3 exhibits high reflectivity and optical absorption in the far ultraviolet region. Notably, Y2O3 demonstrates a remarkable 95% reflectivity in the far ultraviolet region, highlighting the immense potential of R2O3 in designing and applying optical devices. The theoretical calculation data in this paper provide a theoretical basis for related experiments.

In this work, the characterization of zinc nitride (Zn3N2) Thin-film Transistors (TFTs) as phototransistors is presented. Polyethylene terephthalate is used as recyclable plastic substrate. A zinc oxide (ZnO) film is used as passivation layer. The Zn3N2 and ZnO films are deposited at room temperature using a magnetron sputtering. The sensitivity, responsivity and detectivity were extracted and analyzed. Interestingly, a relation between the maximum value of detectivity and the threshold voltage VT was found. Moreover, the electrical characteristics are analyzed after 100 days on air to evaluate the stability under ambient conditions. To the best of our knowledge, the characterization of Zn3N2 TFTs as phototransistors is presented for the first time.
