For metals there is a connection between the thermal conductivity and electric conductivity (Wiedemann–Franz law). However specific heat is not directly related. This is because electric and thermal conductivity are due to the electrons, however the specific heat is mostly due to the ion vibrations (phonons).

Thermal conductivity is determined by the linear slope of ΔT vs. log(ω) curve. The main advantages of the 3ω-method are minimization of radiation effects and easier acquisition of the temperature dependence of the thermal conductivity than in the steady-state

### Mediate relation between electrical and thermal …

Due to the difficulties of a direct relation, within this study a modular approach of a mediate correlation between electrical and thermal conductivity was investigated. Therefore, a direct relationship between a corrected electrical conductivity and water content as well as the standard and simple thermal conductivity model of Kersten (Bull of the Univ Minnesota 28:1–227, 1949) was used.

### Negative correlation between in-plane bonding …

The effects of in-plane (IP) and cross-plane (CP) interatomic bonding strengths on the IP and CP thermal conductivities of a model layered material are investigated using molecular dynamics and lattice dynamics. Increasing the IP bonding strength while holding the CP bonding constant increases the IP thermal conductivity, but reduces the CP thermal conductivity. Analogous but weaker trends are

The minimum thermal conductivity coefficient was found at the lowest total porosity value by means of the highest median pore diameter-area and median pore diameter-volume values.

### Thermal Conductivity and the Wiedemann-Franz Law

Gases transfer heat by direct collisions between molecules, and as would be expected, their thermal conductivity is low compared to most solids since they are dilute media. Non-metallic solids transfer heat by lattice vibrations so that there is no net motion of the media as the energy propagates through.
