Q. How does doping silicon change the thermal conductivity?

A. Doping silicon with other atoms will decrease the thermal conductivity. Since normal doping levels are from 1015 to 1018 atoms/cc, or from 0.1 parts per million to 100 parts per million atoms, the effect of dopant atoms will be much less than the effect of silicon isotope atoms (80,000 parts per million). Highly doped silicon-28 will have higher thermal conductivity than highly doped natural silicon
