摘要: In this paper, we report on the growth of high quality In (x) Al1-x N/GaN hetero-structures on Si substrate by metal organic chemical vapor deposition with various indium compositions (x = 10.2, 16.2 and 17.6%). The lattice-matched In0.176Al0.838N/GaN structure shows a smooth surface with good crystalline quality. In addition, the ultraviolet photodiode device shows excellent device characteristics with a low leakage current of 0.12 A mu A, and a high spectral response. It has good quantum efficiency of 94 mA/W and 44% at 265 nm which is comparable to that of the InAlN photodiode grown on sapphire substrate.
