Summary: This study characterizes the adsorption, self-assembly, and electronic structure of [5,5]-C-90 fullertube molecules on different noble metal surfaces using scanning tunneling microscopy and spectroscopy. The results show that the shape of the molecular orbitals of the adsorbed fullertubes matches the theoretical calculations, and some of the molecular orbitals are influenced by the quantum confinement imposed by the hemifullerene caps. These findings provide a conceptual framework for the design and understanding of custom fullertube molecules.

Summary: We conducted density functional theory computations to investigate the detection capability of a Ti-doped boron nitride graphyne-like nano-sheet (TBNNS) for cyclophosphamide (CP). Our computational results showed that doping the Ti atom in BNNs increases sensitivity and reactivity towards CP, leading to an energy release of -27.23 kcal/mol upon interaction. The electronic conductivity of TBNNS was significantly enhanced by the presence of CP, making TBNNS a promising electronic sensor for CP detection.

Summary: In this study, a series of h-BN/B1-xAlxN heterojunctions with different Al components were fabricated by RF magnetron sputtering, and the performance of the heterojunctions was measured via I-V characteristic representation. The h-BN/B0.89Al0.11N heterojunction exhibited the best performance due to high lattice matching. XPS analysis revealed a type-II (staggered) band alignment in this heterojunction, and DFT calculation further confirmed the existence of a built-in field and an Al-N covalent bond at the interface. This work provides a pathway for the construction of ultrawide band gap heterojunctions for next-generation photovoltaic applications.

Summary: In this study, we theoretically investigate the pump-probe response and the four-wave mixing spectrum in a hybrid system composed of a semiconductor quantum dot and a spherical metal nanoparticle. Using a density matrix methodology, we calculate the absorption/gain, dispersion, and four-wave mixing spectra, and analyze their spectral characteristics. We also apply the metastate theory and the dressed-state picture to predict the positions of the spectral resonances.

By analyzing quantum entanglement measures such as entanglement negativity and entropy, the effect of non-Hermitian imaginary hopping on the system is explored. It is found that in the large... limit, the non-Hermiticity reverses the behavior of the ground state energy and low-lying excitations.

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: In this work, a theoretical model is proposed to achieve the controllability of quantum interference and decoherence. The effects of intralead Coulomb interaction, interdot tunneling, and electron-phonon interactions on differential conductance are investigated. The results show the appearance of destructive interference, Fano interference, and negative differential conductance in strong dot-lead tunneling regions, while a characteristic pattern of positive and negative differential conductances appears in the weak dot-lead tunneling regime.

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.
