The effects of electron heating in free-standing n<SUP>+</SUP> GaAs wires have been studied over the temperature range 0.45 K - 4.2 K. The results indicate that for low lattice temperatures and heating currents the thermal transport in the wires is dominated by the electronic contribution. However, for lattice temperatures above 1 K, an additional contribution to the thermal conductivity is observed that cannot be accounted for by the Wiedemann-Franz law.
