Ga2O3 has emerged as a promising ultrawide bandgap semiconductor for numerous device applications owing to its excellent material properties. In this paper, we present comprehensive review on major advances achieved over the past thirty years in field of Ga2O3-based gas sensors. We begin with brief introduction polymorphs and basic electric properties Ga2O3. Next, provide an overview typical preparation methods fabrication Ga2O3-sensing developed so far. Then, will concentrate our discussion state-of-the-art sensor devices put emphasis seven sophisticated strategies improve their gas-sensing performance terms engineering optimization. Finally, give some concluding remarks forward suggestions, including (i) construction hybrid structures two-dimensional materials organic polymers, (ii) combination density functional theoretical calculations machine learning, (iii) development optical sensors using characteristic spectra future novel

The production and application of beta-phase gallium oxide (β-Ga2O3) single crystals—an emerging ultrawide bandgap semiconductor—is frequently coupled with high temperature mechanical load. Understanding the anisotropic properties at is crucial for optimizing high-performance β-Ga2O3, enhancing its stability reliability in high-temperature environments. Selective nanoindentation conducted on unintentional-doped (100)-grown β-Ga2O3 wafers both room (RT) a (HT) 600 °C, by aligning one facet Berkovich indenter parallel to either [001] or [010] low-index directions (100) surface. direction exhibits higher Young's modulus (E) lower hardness (H) compared RT. deformation morphology confirmed that deformed zones were localized under while more homogeneously distributed direction. Under HT, E H decreased different extents directions, where mechanisms noted. These findings can provide guidance ultra-precision machining HT applications monocrystalline β-Ga2O3.

2 in. bulk β-Ga2O3 single crystals are successfully grown by the edge-defined film-fed growth method with a homemade furnace system. By considering significance of wafer quality in future mass manufacture, nine-point characterization is developed to evaluate full-scale processed (100)-orientated single-crystal wafers. Crystalline and structural characteristics were evaluated using X-ray diffraction Raman spectroscopy, revealing decent crystalline mean full width at half-maximum value 60.8 arcsec homogeneous bonding structures. The statistical root-mean-square surface roughness, determined from nine scanning areas, was found be only 0.196 nm, indicating superior quality. Linear optical properties defect levels further investigated UV–visible spectrophotometry photoluminescence spectroscopy. high wafer-scale wafers meets requirements for homoepitaxial substrates electronic photonic devices vertical configurations.
