Schottky barrier diodes of Au-n-AlGaN grown by OMVPE were obtained and characterized between 77 K and 373 K. Under forward bias the value of the ideality parameter n = 1.41 and the threshold voltage is 0.75 V. The reverse bias leakage current is below 10-10 A on a reverse bias of 10 V. The barrier height (ΦB) was determined to be (1.17 +/- 0.03) eV and (1.3 +/- 0.05) eV by the I-V and the C-V measurement respectively.
