Paper Abstract

The investigation of the thermal conductivity of diamond films gives us a very important information about mechanisms of heat transport and scattering processes in bulk. 1 . Iffrom the specific heat one can obtain characteristics of interaction between atoms and molecules, the study of the transport characteristics (electric and thermal conductivity, thermopower and so on) gives the information about scattering processes in phonon and electronic systems and scatterings on defect structures in solids. 2. The knowledge of absolute values of the thermal conductivity is the necessary for practical application of diamond films as a high heat transmission substrate. 3 . Diamond is a very convenient model system with very high Debye temperature (E 22OO K) for studies the phonon scattering processes in a wide temperature range. The room temperature is low temperature for diamond in comparison with any another materials. The phonon wave length is of the order of ten lattice parameter d3O A at room temperature and ofthe order 500 d '- 1500 A at helium temperatures.
