# Thermal conductivity - doped silicon

I 'trying to find the thermal conductivity of a silicon substrate doped with boron with known dopant concentration. Is there any way to calculate it or it has to be measured.

You may already know this, but the thermal conductivity of single crystal silicon at normal temperatures is only weakly dependent on doping. The dependence is probably less than the measurement error (I typically see values ranging from 149-157 W/m-K). How precise an answer do you need?

I want to know the conductivity of doped silicon with boron at room temperature. An estimation would be wright too. I have to different concentrations of boron, one of 8e18 (cm-3) and one of 1,2e15 (cm-3).
