Summary: In this study, the electronic and magnetic properties of nitrogen monolayer and bilayer doped with carbon and boron were investigated using first-principles calculations. It was found that carbon doping induces strong spin polarization near the Fermi level, leading to magnetic semiconductor nature, while boron doping results in reduced band gap for all considered systems. Co-doping effects are a combined result of separate carbon and boron doping. The results suggest an efficient method to functionalize nitrogen monolayer and bilayer for practical applications in optoelectronic and spintronic nano devices.

Summary: A new two-step metallic alloy-assisted epitaxial growth approach has been demonstrated for producing wafer-scale vertical hexagonal boron nitride/graphene (h-BN/Gr) heterostructures with clear interfaces. The heterostructures maintain high uniformity while scaling up and thickening, and the layer number of both h-BN and graphene can be independently controlled. Conductance measurements confirm the disappearance of electrical hysteresis on h-BN/Gr field-effect transistors, attributed to the h-BN dielectric surface, paving the way for next-generation graphene-based analog devices.

Summary: This paper investigates the adsorption and sensing properties of transition metal-doped WSSe gas-sensitive devices towards H2, CO, and CO2 gases related to thermal runaway in Li-ion batteries using density functional theory. The results show that Ti, Mn, and Mo dopants preferentially bind to the S-surface of the WSSe monolayer, and all three monolayers exhibit significantly improved sensing characteristics, with chemisorption towards CO. Band structure analysis suggests that the Ti-WSSe monolayer has the potential to be used as a resistive CO detection sensor. Recovery time calculations indicate the reuse capabilities of the gas-sensitive devices. Mn-WSSe monolayer shows potential for H2 detection, while Mo-WSSe monolayer is more suitable for CO2 detection. This work lays the foundation for potential gas-sensitive applications of WSSe monolayer in thermal runaway scenarios, advancing research in gas sensing domains.

Summary: This paper investigates the effects of electric and magnetic fields on the Goos-Hanchen (GH) shift in a semi-Dirac system. The results show that the magnitude and direction of the GH shift depend on various factors such as incidence angle, electric barrier height and width, and magnetic field. It is observed that there is a saltus step in GH shifts at the critical magnetic field, which decreases with increased potential barrier thickness. Additionally, the GH shift can be significantly enhanced by applying an electric field in the III region. These findings are important for the development of semi-Dirac based electronic devices.

Summary: Using full electron-phonon interactions and the Boltzmann transport equation, this study investigates the phonon scattering channel and electrical properties of graphene under anharmonic phonon renormalization (APRN). The results show that the APRN reduces the phonon frequency and three-phonon phase space with increasing temperature, affecting the acoustic branch more than the optical branch. The thermal conductivity of graphene decreases after considering three- and four-phonon scattering, and the primary scattering channels are identified. Furthermore, the APRN increases the strength of electron-phonon coupling and leads to an increase in n-type electric resistance at room temperature.
