Electron heating effects in free-standing single-crystal GaAs fine wires
Electron heating effects in free-standing single-crystal GaAs fine wires
We report on experiments and their analysis of electron heating effects in 3.2 µm long free-standing fine wires (triangular cross-section with ~0.5 µm side) of single crystal GaAs doped at 1017 cm-3. The data can be used to extract a thermal conductivity which has a linear temperature dependence, consistent with a contribution from electrons and/or one-dimensional phonons. We show that the electronic contribution dominates.

Abstract
We report on experiments and their analysis of electron heating effects in 3.2 µm long free-standing fine wires (triangular cross-section with ~0.5 µm side) of single crystal GaAs doped at 1017 cm-3. The data can be used to extract a thermal conductivity which has a linear temperature dependence, consistent with a contribution from electrons and/or one-dimensional phonons. We show that the electronic contribution dominates.
