Abstract
A Si-integrated oxide-nitride deep-ultraviolet photodetector with remarkable photosensitivity is demonstrated. The proposed device topology is realized through the disordered nucleation of β-Ga2O3 crystals on monocrystalline TiN interlayers forming an oxide-nitride vertical heterostructure stack housed on a Si substrate. Spectral responsivity levels of about 240 A/W at illuminating power density levels of around 7.40 μW/cm2 were achieved.
