Low temperature electrical and magnetoresistance measurements have been performed on free-standing wires of single-crystal n-type GaAs of length 3.2 µm and width 0.55 - 0.6 µm. In addition, electric field heating experiments have shown that the thermal conductivity, even for doping concentrations as low as 10<SUP>17</SUP> cm<SUP>-3</SUP>, is dominated by the electronic contribution and can be adequately explained by invoking the Wiedemann-Franz law.
