4.2.3 Thermal Conductivity - TU Wien
Several expressions exist for the thermal conductivity of semiconductor alloys. As an example, Adachi et al. [ 303 ] use one based on Abeles''s complex model [ 304 ]. However, an even more straightforward approach is proposed in [ 305 ], where a harmonic mean is used to model the conductivity at 300 K, while the exponent is linearly interpolated as there is no experimental data for temperatures
