Summary: Wafer bonding of β-Ga2O3 and N-polar GaN single crystal substrates, achieved by adding ZnO as a glue interlayer, resulted in fully bonded wafers without Newton rings. Temperature-dependent current-voltage measurements revealed the impact of post-annealing temperature on the electrical and structural characteristics of the bonded samples. Annealing the bonded wafers at 1100°C in N-2,N- environment consistently produced ohmic-like characteristics, attributed to the crystallization of ZnO and diffusion of Ga into ZnO. This work demonstrates promising wafer bonding of β-Ga2O3 and GaN, with potential applications in high-frequency and high-power devices.

Summary: The difficulty of fabricating ohmic contacts on wide bandgap semiconductors like 13-Ga2O3 is addressed by inserting an n+-doped metal oxide layer between metal and the semiconductor layers. Pulsed laser deposition was used to deposit high crystallinity films of 13-Ga2O3, Erbium-doped ZnO (ErZO), and Gallium-doped ZnO (GZO). Investigation of the band offsets and electrical properties of ErZO/13-Ga2O3 and GZO/13-Ga2O3 heterojunctions revealed nested gap (type I) structures. The solar blind UV detector with a fork electrode structure of as-grown 13-Ga2O3/ErZO/Ti/Au showed superior performance due to ErZO's low band offset and small work function difference.

Summary: Due to the difficulty of p-type doping in beta-Ga2O3, the NiO/beta-Ga2O3 heterojunction is considered as a promising candidate for bipolar devices. In this study, the band alignment and electrical properties of NiO/beta-Ga2O3 heterojunctions with different beta-Ga2O3 orientations were comparatively studied. It was found that there is a type-II band alignment between NiO and beta-Ga2O3, and the valence band offsets and conduction band offsets vary with different substrate orientations. The influence of substrate orientations on the properties of NiO/beta-Ga2O3 heterojunctions is of great importance for the design and optimization of beta-Ga2O3-based heterojunction devices.

Summary: This report presents the research results on the electronic structure of three interfaces consisting of organic layers of Alq(3), Gaq(3), or Erq(3) deposited on GaN semiconductor. The formation and characterization of the interfaces were performed in situ under ultrahigh vacuum conditions. The band energy diagrams of the substrate and interfaces were constructed using ultraviolet photoelectron spectroscopy (UPS) assisted by X-ray photoelectron spectroscopy (XPS). The study found that the highest occupied molecular orbitals (HOMOs) of Alq(3), Gaq(3), and Erq(3) layers are at 1.2, 1.7, and 2.2 eV, respectively. The Alq(3) layer does not affect the position of the vacuum level of the substrate, unlike the Gaq(3) and Erq(3) layers, which lower it by 0.8 eV and 1.3 eV, respectively. The interface dipoles at the phase boundaries were found to be -0.2, -0.9, and -1.2 eV for Alq(3), Gaq(3), and Erq(3) layers on GaN(0001) surfaces.

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.
