Abstract
The authors report on the results of measurements of low frequency noise in thin (60 nm) Si-doped n-type gallium nitride (GaN) films grown on sapphire. At room temperature, the noise spectra have the form of 1/f noise with a Hooge parameter α~2×10-3. This value of α is three orders of magnitude smaller than that observed before in thin films of n-GaN
