(a) Deviations between ΛA(f) for Si, Si:B, Si0.99Ge0.01, Si0.2Ge0.8 and Ge (markers) at w0=10 μm and bulk thermal conductivity values (dashed lines). Solid lines are the predictions of a ballistic/diffusive model for thermal transport. (b) Deviations between ΛA(w0) for Si, Si:B, and Si0.99Ge0.01 at f=1.1MHz (makers) and their bulk thermal conductivity values (dashed lines). Solid lines are the predictions of a ballistic/diffusive model for thermal transport.
