Summary: This work explores the effect of hydrogen (H) on the electronic properties of 4H silicon carbide (4H-SiC) and evaluates its passivation on intrinsic defects. It is found that interstitial H at different locations dominates the defect configurations in p-type and n-type 4H-SiC. Compensation of interstitial H in n-type 4H-SiC hinders the increase of electron concentration. H passivation of carbon vacancies improves the carrier lifetime of moderately doped 4H-SiC. Thermal annealing is needed to promote the uniformity of V-Si arrays. This study provides insights for impurity engineering in 4H-SiC.

Summary: Researches have developed a novel strategy to enhance the sensing performance of p-type NiO by utilizing the unique functional properties of self-assembled monolayers. By modulating the hole concentration near the surface of NiO nanowires using terminal epoxy groups, the electron transfer from reducing gases to the nanowires' surface is increased. As a result, the SAM-functionalized sensors exhibit a 9-fold higher response at low temperatures compared to bare NiO nanowires.

Summary: Exposing amorphous In-Ga-Zn-O (a-IGZO) thin-film transistors (TFTs) to deep ultraviolet light (lambda =175 nm) results in a rigid negative threshold-voltage shift, subthreshold hump, and increase in subthreshold-voltage slope, attributed to photo creation and ionization of oxygen vacancy states (V-O). The hump is caused by the highly conductive backchannel and can be suppressed by reducing the a-IGZO film thickness or applying a back bias after radiation. The instability is mainly due to ionized V-O and can be minimized by understanding and controlling the ionization process.

Summary: MXenes are two-dimensional inorganic materials with abundant surface sites that can improve capacitor performance when morphology and surface groups are controlled. Introduction of ions can replace surface termination groups, leading to superior capacitance performance. However, metal ion abduction may have negative effects on electrochemical properties due to oxidation of high-valent metal ions.

Summary: In this study, the tensile mechanical behavior of monolayer XN (X = Ga, In) was investigated using molecular dynamics simulations. The effects of temperature and point vacancies on fracture stress, strain, and elastic modulus were studied. It was found that increasing temperature and the presence of vacancies result in a decrease in elastic modulus, tensile strength, and fracture strain. The mechanical behaviors of these materials also exhibit substantial anisotropic nature. The study provides insights into adjusting tensile mechanical behaviors by introducing vacancy defects and offers guidance for the applications of XN (X = Ga, In) in flexible nanoelectronic and nanoelectromechanical devices.

Summary: The study examined the structural stability and electronic properties of lateral monolayer transition metal chalcogenide superlattice nanoribbons, focusing on the effects of varying width, periodicity, cationic and anionic elements, biaxial strain, and edge passivation on the band gap. Various combinations of elements for passivation were found to affect the energy band gap, with differences in band gap states observed between edge and inside vacancies. The electronic orbitals around Mo vacancies were found to play a crucial role in determining band gap properties.

Summary: The carrier dynamics in various types of epitaxial graphene layers on SiC substrates were studied using TARPES. Layer-dependent electron doping was observed in the Dirac bands of quasicrystalline bilayer graphene, resulting in the generation of transient voltage between the upper and lower layers. The amount of photoinduced carrier transport depends on the distance from the substrate. Comparison of TARPES results between flat and stepped SiC substrates suggests that the doping carriers likely originate from interface step states.

Summary: This review focuses on the study of chiral degrees of freedom in matter and electromagnetic fields, discussing the recent observations of the chiral-induced spin selectivity effect and the nanophotonic strategies designed to amplify chiral light-matter interactions. The CISS effect offers opportunities for spin control and the design of room-temperature quantum devices, while chiral-optical effects could have advantages in all-optical and quantum information technologies. The review presents a vision for the future roles of chiral-influenced quantum effects in enabling room-temperature quantum technologies.

Summary: The chirality-induced spin selectivity (CISS) effect allows for controlling spin-dependent chemical reactions, such as photoinduced water splitting. This effect has been observed in organic chiral molecules, but its emergence in chiral inorganic materials is still not well-understood. In this study, chiral CuO films were deposited on partially UV-transparent gold substrates and subjected to deep-UV laser pulses. The spin polarization of photoelectrons was measured and found to be energy dependent, suggesting a contribution from the CISS effect in addition to intrinsic spin polarization in the CuO film.

Summary: In this article, we discuss the manifestation of the chirality-induced spin selectivity (CISS) effect in photoelectron spectroscopy experiments. We evaluate various systems and observe high spin polarization values, with the longitudinal spin orientation changing sign with a change of the enantiomeric form. Recent advances allow for distinguishing the contributions of electrons with different kinetic energies to the electron spin polarization, and thus distinguish the CISS effect from bulk contributions to the spin originating from different mechanisms.

Summary: Several thiophene terminated thienoacenes with different alkylation positions on the terminal thiophene rings were synthesized and characterized. The molecular stacking and physicochemical properties were found to be effectively tuned by the alkylation. The OTFTs based on 2,8-dioctyl-naphtho[2,3-b:6,7-b '] bithieno [2,3-d] thiophene (2,8-C8NBTT) exhibited the highest mobility of 3.58 cm2 V-1 s-1 and a remarkably high current on/off ratio. Furthermore, the organic phototransistors based on 2,8-C8NBTT demonstrated higher photosensitivity, photoresponsivity, and detectivity compared to the other derivatives NBTT and 3,9-dioctyl-naphtho[2,3b:6,7-b '] bithieno [2,3-d] thiophene (3,9-C8NBTT).

Summary: A recently proposed concept allows for obtaining much shorter pulses in Self-Amplified Spontaneous Emission Free Electron Lasers (SASE FELs) by suppressing radiation in the long main undulator while preserving microbunching within a shorter lasing slice. The method of excessive reverse undulator taper is discussed and illustrated numerically in this paper, with first experimental tests performed at the soft X-ray FEL user facility FLASH. The measured pulse duration approaches 1 fs (FWHM) at the wavelength of 5 nm.

Summary: We investigate the electron emission from 3D chiral silver alloy nanohelices initiated by femtosecond laser pulses. We find hot but thermally distributed electron spectra and a strong anisotropy in the electron yield with left- and right-circularly polarized light excitations, which invert in sign between left- and right-handed helices. Measurements of the reflectance and simulations of the absorbance of the helices based on retarded field calculations are compared to the anisotropy in photoemission.

Summary: Conjugated polymers based on diketopyrrolopyrrole (DPP) are important high-performance organic semiconductors. N-alkylation is necessary for the solution synthesis of DPP-based CPs, while oxidative chemical vapour deposition (oCVD) provides a solventless and scalable approach for the polymerisation of N-unsubstituted DPP. The oCVD reaction of TDPP yields polymer thin films with H-bonding and conjugated covalent bonds, resulting in higher conductivity and increased lifetime of electronically excited states compared to N-alkylated counterparts.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
