High Performance Solar-Blind Ultraviolet \(320 \times 256\) Focal Plane Arrays Based on AlxGa1-xN
We report on solar-blind ultraviolet, AlxGa1-xN-based, p-i-n, focal plane array (FPA) with 92% operability. At the peak detection wavelength of 278 nm, \(320 \times 256\) -FPA-pixel showed unbiased peak external quantum efficiency and responsivity of 49% and 109 mA/W, respectively, increasing to 66%...

| Zusammenfassung: | We report on solar-blind ultraviolet, AlxGa1-xN-based, p-i-n, focal plane array (FPA) with 92% operability. At the peak detection wavelength of 278 nm, \(320 \times 256\) -FPA-pixel showed unbiased peak external quantum efficiency and responsivity of 49% and 109 mA/W, respectively, increasing to 66% under 5 V of reverse bias. Electrical measurements yielded a low-dark current density: |
