I. GaAs Material Properties - NASA
Lattice scattering , which is a result of thermal vibrations of the lattice, increases with temperature and becomes dominant at high temperatures; therefore, the mobility decreases with increasing temperature.

Chapter 4. Basic Failure Modes and Mechanisms
parts.jpl.nasa.govThis failure mode is generally observed in devices subjected to an accelerated life test or to high operating temperatures. The degradation is observed as an increase in the gate leakage current over the duration of the test. No experimentally identified failure mechanisms have been linked to this failure mode, but surface-state effects have been

This screening must be built into the description of the harmonic lattice vibrations which defines the noninteracting phonons.
