Aldo, most diamonds are good thermal conductors, but electrical insulators, investigation of thermal and electro conductivity can be used for distinguishing it from other materials and identifying impurities in a genuine diamond. Synthetized diamonds show different properties. The knowledge of basic properties of the materials allows better using of their applications in different scientific and other areas. By experimental procedures, it is observed interesting phenomena, that if electrical conductivity is increasing, the thermal conductivity has reciprocal behavioral. Considering that grain size is very small in deposited films of synthetized diamonds, there are a lot of grain boundaries on entire volume of film. This leads to very complex electronic transport properties which are different to commonly used lattice-based band approximations. Electronic properties can be improved by involving impurities. Analysis of this phenomena is subject of this paper.
