We present an analytic theory of hot-electron transport in a GaN quantum well containing a large-enough electron concentration for strong electron-electron scattering to establish a drifted distribution. Novel behaviour includes the squeezed electron distribution and absolute cooling of the electron gas in a strong electric field when the electron temperature decreases with increase of the electric field. The current-voltage characteristics have the regions which obey the s-type dependence.
