Summary: Pulsed laser deposition was used to fabricate as-grown amorphous and post-growth annealed crystalline beta-Ga2O3 films. The films annealed at temperatures above 600 degrees C exhibited a pure monolithic phase with a large bandgap. The thermally activated donor ionization and dielectric relaxation were investigated in these films, revealing the presence of donor levels and small polaron tunneling relaxation in the as-grown amorphous Ga2O3 film but not in the monolithic beta-Ga2O3 film.

Summary: This study achieved high permittivity and low dielectric loss in Ga ion-implanted Cu-doped ZnO films through optimized doping concentrations and annealing processes. The high permittivity film exhibited good stability and worked effectively across a wide frequency range. The enhancement of permittivity was attributed to the correlated potential barrier hopping of electrons between defect states created by co-doping.

Summary: Ion implantation is an effective method for introducing defects into semiconductors. In this study, we investigated the use of crystallographically aligned implants to control the balance between optically active defects in ZnO. Optical data and structural analysis confirmed the formation of different dominant crystalline defects in samples implanted along and off the [0001] direction. The proportions of extended and point defects in the initial as-implanted states of these samples were found to significantly influence the defect-related luminescence upon annealing. We conclude that channeling implants have value in functionalizing defects in semiconductors by tuning specific spectral contents in defect-related emission bands.

Summary: This study fabricates monoclinic phase (BixGa1-x)2O3 ternary alloys on c-plane sapphire via magnetron co-sputtering and investigates their electrical properties. It is found that alloying Ga2O3 with Bi2O3 decreases the bandgap and lowers the self-trapping energy for holes. The conductivity of (Bi0.04Ga0.96)2O3 film is lower than that of undoped Ga2O3, likely due to the compensation of shallow donors by acceptors activated by Bi2O3-induced upward shift of the valence band edge.

Summary: High precision nanorod based surface morphologies can simulate the function of sensory hairs with nanotechnology. The unique gas sensitive I-V characteristics of these surfaces require initialisation under voltage bias and temperature elevation to exploit their band structures and achieve optimal gas response. Optimising nanorod based sensors with effective approaches can provide efficient control to downsize and miniaturise current gas sensors. By using ultraviolet photoelectron spectroscopy (UPS), specific band structure parameters can be extracted to determine the optimal sensor initialisation bias. The results validate the correlation between the fabricated nanostructured Schottky barrier heights obtained from UPS data and their I-V data, and also demonstrate the experimental validity of the proposed band structure. The optimal biasing condition of 0.8 V is determined for Au-ZnO nanorod hydrogen gas sensory operation at 150 degrees C, and the gas response data exhibit exponential dependence with gas concentration, which is highly relevant for programmable trigger response controlled sensing function based applications.

Summary: Recently, a MAPbBr(3)/MAPbCl(3) bulk heterostructure was constructed by splicing a MAPbBr(3) and a MAPbCl(3) single crystal. This heterostructure photodetector demonstrated dual-band optical detection capabilities, with fast switching time and high responsivities at different wavelengths. The ability to extract photo-carriers separately from crystals with different band gaps provides a potential solution for dual-wavelength light communications in the future.
