BETA-GA2O3 SINGLE-CRYSTALSGROWTHLAYERSThe resistance to deformation and crack formation in epitaxial layers of metastable alpha- and epsilon(kappa)-Ga2O3 polymorphs grown on sapphire substrates has been studied by nanoindentation techniques. The epilayers of alpha-Ga2O3 (0001) and epsilon(kappa)-G...
Gallium oxide (Ga2O3) has especially become popular because of its established applications in semiconductors. Of five polymorphs, monoclinic β-Ga2O3 is the most thermodynamically stable phase. However, orthorhombic Ga2O3 (also known as ε-Ga2O3 or κ-Ga2O3) is gaining increasing interest due...
A epsilon-Ga2O3 metal-semiconductor-metal solar blind ultraviolet photodetector with large on/off ratio of over 2 x 10(3), peak responsivity of 146 A/W and detectivity of 1.2 x 10(13) Jones was fabricated, indicating good optical properties of the epsilon-Ga2O3 film....
Physical properties of kappa- and epsilon-Ga2O3 are investigated using density functional theory. We utilized the supercell method considering the partial occupancies in epsilon-Ga2O3. The polarization values of these materials were analyzed to overcome the inconsistency between experimental and ...
Herein, a poly(N-vinyl carbazole) (PVK)/epsilon-gallium oxide (epsilon-Ga2O3) heterojunction device was fabricated by spin coating prepared PVK solution onto a epsilon-Ga2O3 thin film produced by metal-organic chemical vapor deposition. Under 254 nm ultraviolet light, the device shows obvious ...
