I am in need to have Temperature dependent data for Lattice specific heat and thermal conductivity of Indium Tin Oxide (ITO) for bulk as well as thin-film case.
Dear Amardeep,
the accurate values for ITO I don't know. But I can help to determine these numbers.
- For the specific heat I would apply the "Debye model". The only specific parameter you need is the Debye temperature for this material.
-Due to the fact that ITO has metallic properties, I propose to apply the "Wiedemann-Franz-law". This is at least above room temperature a nice approach. This law is:
lambda/sigma = T*L. L = 2,45*10-8 V²/K² (L-Lorenz number)
The thermal conductivity lambda is related to the electrical conductivity sigma.
Measuring the electrical conductivity as a function of T, you have the thermal conductivity.
With Regard

Dear Amardeep,
I found a paper where you can find the parameter you need. I must correct my opinion that the Wiedemann Franz law is sufficient to calculate the thermal conductivity because the lattice contribution is still the dominant portion.

Rüdiger Mitdank Thank you Sir for your opinion and suggestions, I already read this paper but required specific heat and thermal conductivity data at different temperature for ITO.
