Extrapolated experimental dependence of electron energy relaxation time is used to treat hotelectron sharing by the adjacent Al0.15Ga0.85N and GaN layers in Al0.15Ga0.85N/GaN. The results fit the available experimental data on microwave noise when hot-phonon effect on the energy relaxation time is taken into account. The relaxation time of the occupancy fluctuations of the shared states is estimated to be 6 ps at 80 K lattice temperature.
