Summary: This work demonstrates a high-performance beta-Ga2O3-based solar-blind metal-oxide-semiconductor field-effect phototransistor (SBPT). The SBPT exhibits excellent photoelectrical properties at a gate voltage of 0 V, including a large photo-dark current ratio, high responsivity, large external quantum efficiency, and high detectivity. The ultrahigh photoresponse performance of the device suggests that SBPT working at a gate bias of 0 V provides a potential route for the application of solar-blind photodetectors.

Summary: In this study, Ga2O3 solar blind photodetectors with different metal-semiconductor contact configurations were constructed and their performance was compared. The Ti/Ga2O3/Ti device operated in a photoconductive mode with high responsivity and rejection ratio, but exhibited sub-gap response and high dark current. The Ni/Ga2O3/Ni device operated in a mixed photovoltaic and photoconductive mode with decent photoresponsivity, high rejection ratio, and eliminated slow photoresponse.

Summary: The solar-blind photodetector (PD) converts ultraviolet (UV) light into electrical signals and has broad applications. Gallium oxide (Ga2O3) is a promising candidate for solar blind detection due to its suitable optical bandgap and other key attributes. However, the performance of Ga2O3 PDs based on the metal-semiconductor-metal (MSM) structure still lags behind commercial photomultiplier tubes (PMTs).

Summary: High-performance avalanche photodetectors (APDs) based on amorphous Ga2O3 (a-Ga2O3)/ITO heterojunction have been successfully fabricated, showing ultrahigh responsivity, specific detectivity, external quantum efficiency, and exceptional capability for detecting ultraweak signals under 254 nm light irradiation. The superior performance of a-Ga2O3-based APDs can be attributed to intrinsic carrier transport mechanisms in a-Ga2O3 and modified band alignment at the heterojunctions, providing greater design flexibility for wide applications of emerging Ga2O3 semiconductor with improved performance.

Summary: By investigating the relationship between structure and optical properties, the Nd3+-doped La2CaB8O16 crystal with a long rare-earth ion distance more than 4.27 angstrom was found to allow a high doping concentration and exhibit a weak fluorescence quenching effect. Nd3+-doped La2CaB8O16 crystals with different concentrations were successfully grown by the top seeded solution growth method, showing large size, high optical quality, strong absorption band at 800 nm, and a fluorescence band at 1055 nm. A diode-pumped orthogonally polarized dual-wavelength laser operation at 1052 and 1055 nm was realized, with a slope efficiency of 16.3% and output power of 859 mW. The Nd3+-doped La2CaB8O16 crystal is a promising laser gain medium for 1 μm lasers and possible generation of terahertz radiation.
