-----20 nm
Goal Collect the data and analyze the
difference. It is the basis for
improving the thermopower of Bi2Te3
If the values of thermopower are reasonable, the
thermal diffusivity measurements will be carried
out. It is ready to prepare the paper.
If the values of thermopower are bad, it is
necessary to re-think about materials and
discuss.
