Summary: Spin-polarized density functional theory was used to explore the role of oxygen vacancy, pre-adsorbed oxygen ion, and Pt dopant in CO and acetone sensing on the ZnO surface. It was found that good adsorption energy alone is not enough to determine sensor sensitivity, as all charge transfer modes must be considered. Charge density difference plots revealed a charge transfer mode from acetone to pre-adsorbed oxygen ion, suggesting that direct adsorption of acetone may also play a role in gas sensing.

Summary: This study systematically and comparatively investigates the microstructural, electrical, and magnetic properties of Gd-doped and (Al, Gd) codoped Zn-polar and Opolar ZnO wafers manufactured by the ion implantation method. The results reveal intrinsic ferromagnetic behavior in Gd-implanted polar ZnO wafers enhanced by Al codoping. Furthermore, the saturation magnetization is found to be stronger in doped O-polar ZnO wafers compared to implanted Zn-polar ZnO wafers. The introduction of Al ions into Gd-implanted polar ZnO enables further improvement in ferromagnetism, which is directly related to carrier concentration. First-principles calculations confirm that the interaction between the Gd-4 f state and the O-2p state is stronger in oxygen polar ZnO, resulting in a higher magnetic moment. Moreover, the increased magnetic moment in (Al, Gd) co-implanted ZnO mainly originates from hybridization of Al and O orbitals.

Summary: This study investigated the activation of CO and CO2 on ZnO surfaces, a typical non-reducible oxide and a major catalytic material, using ambient-pressure scanning tunneling microscopy (AP-STM), AP X-ray photoelectron spectroscopy (AP-XPS), and density functional theory (DFT) calculations. The results showed that enhanced physisorption and the concerted interaction of physisorbed molecules led to the formation of new adsorbate structures, facilitating the activation of CO and CO2 on ZnO. The study provided molecular insights into the fundamental chemistry and catalytic properties of ZnO surfaces under realistic reaction conditions.

Summary: This study presents a comprehensive experimental and theoretical investigation on the effects of surface polarity on the structure and ferromagnetic properties of Co and Co-Sm co-implanted polar ZnO films. The results show that O-polar ZnO exhibits stronger ferromagnetism, possibly due to the combination of more oxygen vacancies and larger local moments related to Co and Sm doping.

Summary: The wet chemical etching process of zinc oxide (ZnO) nanowires in radiolytic water was studied using liquid cell transmission electron microscopy (LCTEM). It was found that the dissolution rate of thin nanowires remains constant with reducing diameter, while thick nanowires exhibit complex etching behaviors. The dissolution rate of thick nanowires is constant at first and then increases, and anisotropic etching occurs at both ends of thick nanowires leading to the formation of distinct tips. The polarity difference at the two ends of the nanowire and the arrangement of sidewall cones determine the shape and formation process of the tips.

Summary: This paper presents an improved theoretical view of ab initio thermodynamics for polar GaN surfaces under gallium-rich conditions. The study uses density functional theory (DFT) calculations to systematically investigate the adsorption of gallium atoms on GaN polar surfaces, starting from the clean surface and progressing to the metallic multilayer. The analysis confirms that a monolayer of Ga adatoms on the GaN(000-1) surface is highly stable over a wide range of temperatures and provides a better thermodynamic description of the surface state under conditions typical for molecular beam epitaxy.

Summary: It is possible to evaporate diradicals in a controlled environment to obtain thin films with preserved diradical character, although this process presents challenges. The higher the formation energies of the crystal, the more difficult it is to evaporate intact diradicals, while a large delocalization of unpaired electrons helps the diradical resist evaporation.

Summary: In this study, we demonstrate theoretically and experimentally a strong and tunable optical anisotropy in epitaxially-grown VO2 thin films. We reveal that these films exhibit an ultra-large birefringence through a combination of temperature-dependent X-ray diffraction, spectroscopic ellipsometry measurements, and first-principle calculations. Moreover, by leveraging the insulator-to-metal transition of VO2, we demonstrate a dynamic reconfiguration of optical properties from birefringent to hyperbolic, opening avenues for multi-functional devices with tunable anisotropy and hyperbolic dispersion.

Summary: In this study, we investigate the degradation of radical thin films by comparing two Blatter radical derivatives. We find that the chemical and magnetic properties of the films are affected by interactions with different contaminants. Atomic H and NH2 negatively impact the magnetic properties of Blatter radicals, while molecular water specifically influences the magnetic properties of diradical thin films and contributes to their shorter lifetime in air.

Summary: The article introduces a new physical model that combines multiphonon trap-assisted tunneling (TAT) with hydrodynamic theory to describe electrical conduction in Ovonic Threshold Switching (OTS) devices. By reproducing static and transient electrical responses from Ge(x)Se(1-x) experimental devices, the role of material properties such as mobility gap and defects in tuning OTS performance is outlined. The article also provides a clear physical interpretation of different OTS conduction regimes (off, threshold, on) and a nanoscopic picture of carrier transport processes. The impact of geometry, temperature, and material modifications on device performance is discussed, offering physical insight into OTS device optimization.

Summary: In this study, spinel copper gallate (CuGa2O4) nanocrystals with an average size of 3.7 nm were synthesized and characterized via a heat-up colloidal reaction. The CuGa2O4 nanocrystals have a band gap of -2.5 eV and exhibit p-type character, which is consistent with ab initio simulations. When deposited as thin films, these novel nanocrystals are shown to be photoactive, generating a clear and reproducible photocurrent under blue light irradiation. The ability to adjust the Cu/Ga ratio within the nanocrystals and its effect on their optical and electronic properties was also demonstrated. These findings position CuGa2O4 nanocrystals as a promising material for optoelectronic applications, including hole transport and light harvesting.

Summary: This study investigates Si mass transport and morphological transformations on the Si(111) surface during (root 3 x root 3)-Sn reconstruction formation and Si homoepitaxy. The research shows that the formation of different Sn phases at different temperatures affects the Si island nucleation and monatomic step shift, which in turn impact the morphology of the Sn/Si(111) interface. Electromigration-induced drift of disordered Sn domains leads to enhanced noncompensated Si mass transport and surface roughening.

Summary: Deposition of thallium (Tl) onto the Au/Si(111)5 x 2 reconstruction followed by annealing results in the formation of a surface structure with 4 x 2 periodicity. The immiscibility of Au and Tl leads to the migration of Tl atoms over the Si chains. Thallium donates electrons to the surface, converting the metallic surface into an insulating state and altering the inter-chain distance within the array of Au atomic wires.

Summary: Using ab-initio calculations, the interaction between lead adatom and both clean and doped iron (100) surfaces was investigated. It was found that the lead adatom prefers to adsorb in the hollow site, which is more stable compared to the top and bridge sites, and in this position, it is energetically favorable over the iron adatom. Moreover, lead adsorbed in the hollow site of the iron (100) surface doped with chromium was found to create a more stable system compared to nickel-doped surfaces with an iron adatom in the same position. The study also explored inter-layer distances, bonding mechanisms, magnetic behaviors, and charge density differences. The results provide insights into the role of doping in the interaction between lead adatom and iron surface, and have implications for the analysis of corrosion processes caused by liquid lead.

Summary: Alkaline water electrolysis is a simple and efficient method for renewable hydrogen production, utilizing cheap and abundant transition metals. The catalytic properties of Ni materials are enhanced by the formation of oxidized compounds on the surface. The high electrocatalytic activity of Ni (oxy)-hydroxides is directly related to water intercalation in the passivation layer, supporting the hypothesis of a water mediated OH- diffusion mechanism. The self-organization of the surface structure during passivation layer formation enables high electrode performance.
