Summary: Ultrawide-bandgap semiconductor heterojunctions Sc2O3/GaN and theta-Al2O3/GaN were studied using density functional theory (DFT). The dielectric-dependent hybrid (DDH) functional, which accurately describes the dielectric screening in wide-bandgap materials, was used. The calculated band gaps matched with experimental measurements, and both heterojunctions exhibited type-I band alignments with specific valence/conduction band offsets. This study provides a method for predicting band offsets in other wide-bandgap semiconductor heterojunctions.

Summary: This study investigates the impact of different crystallographic structures of sputter-deposited TiO2 n-type window layers on the power conversion of TiO2/Se photovoltaic devices. The efficient photovoltaic conversion of TiO2/Se devices requires improving carrier collection in the Se layer and reducing recombination at the TiO2/Se interface. TiO2 window layers with varying anatase and rutile crystallographic structures were applied to TiO2/Se heterojunction devices. The power conversion efficiency of TiO2/Se photovoltaic devices was increased from 3.04% to 4.48% in devices with anatase/rutile mixture window layer.

Summary: The profiles of the valence subbands in an AlGaN-based quantum well are studied, considering quantum confinement effect and strain. Increasing the quantum confinement effect and compressive strain raises the relative position of the heavy hole subband to the crystal field splitting hole subband in the valence band. However, the underlying mechanisms of the modulation by the quantum confinement effect and strain are different. In addition, if the energy level between the heavy hole and crystal field splitting hole subbands is close, the subband anti-crossing effect enhances their coupling and leads to dipole moment transformation between the conduction and valence subbands. These findings have important implications for the design of AlGaN-based optoelectronic devices with short wavelength, high carrier injection, or monolithic integration.

Summary: This study demonstrates the control of interfacial adhesion in III-nitride van der Waals epitaxy (vdWE) by using graded high-temperature nitridation treatment of the graphene insertion layer. Different epitaxial modes were achieved based on the adhesion difference, and the quasi-vdWE enabled by small graphene defects and proper N doping showed the lowest formation energy for AlN nucleation. The successful transfer of III-nitride onto a flexible substrate using a UV resin-assisted bonding technique allows for the fabrication of a flexible photodetector with high device yield and excellent performance after bending cycles. This work offers a promising strategy for controlling vdWE interfacial adhesion and enables the development of future UV foldable and wearable devices.

Summary: Gamma-cyclodextrin-based metal-organic frameworks (gamma-CD-MOFs) have been successfully prepared with a modified vapor diffusion method, showing great potential as a biocompatible porous material for carrier-based drug delivery. Encapsulation of oregano essential oil (OEO) in gamma-CD-MOFs did not alter their crystal structure and increased their thermal stability. In vitro experiments demonstrated that gamma-CD-MOFs exhibited excellent release control. Therefore, gamma-CD-MOFs can serve as an effective carrier for delivering OEO.

Summary: III-nitride materials like AlN, GaN, and InN have promising applications in the semiconductor industry, but the high defect densities resulting from the growth process can impact device performance. In this study, a first-principles investigation was conducted to understand the growth and electronic properties of stacking mismatch boundaries (SMBs) in III-nitride materials. The study revealed that SMBs can be categorized into three types based on the terrace edge of the coalescent normal and stacking-fault regions, and the type can be controlled by varying the chemical potential and initial nucleation size during growth. It was also found that SMBs produce in-gap states with various properties, such as itinerant magnetism and optical transition.

Summary: We proposed an alternative strategy to optimize the metal/n-AlGaN contact by introducing a heterostructure with a polarization effect and by etching a recess structure through the heterostructure beneath the n-contact metal. This strategy could simultaneously decrease the Schottky barrier height as well as provide a better carrier transport channel, enhancing both the thermionic emission and tunneling processes. This investigation provides an alternative approach to obtain a good n-contact, especially for Al-rich AlGaN-based devices, such as diodes and LEDs.

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.
