β-Ga 2 O 3 is emerging as an interesting wide band gap semiconductor for solar blind photo detectors (SBPD) and high power field effect transistors (FET) because of its outstanding material properties including an extremely wide bandgap (Eg ∼4.9eV) and a high breakdown field (8 MV/cm). This review summarizes recent trends and progress in the growth/doping of β-Ga 2 O 3 thin films and then offers an overview of the state-of-the-art in SBPD and FET devices. The present challenges for β-Ga 2 O 3 devices to penetrate the market in real-world applications are also considered, along with paths for future work.
