Abstract
The fabrication and characterisation of an 8×8 Schottky barrier photodiode array on GaN, with pixel size of 200×200 μm, are reported. This array shows an average peak response of 0.05 A/W and sharp cutoff at 360 nm. Decay time measurements reveal the response to be PC-limited with a time constant of 50 ns. The visible-blind UV-imaging capability of the GaN photodiode array is also demonstrated for the first time
