DETAIL FOR POSTDOCTOR RESERARCH
The emergence of superconductivity seems to be closely linked to the thermopower, and
there is a close correlation between Tc and the abnormally enhanced part of thermopower,
both showing a similar dome-like doping dependence, the insights for the reasons of enhanced
thermopower for all the iron-based arsenide superconductors may give a clue for
superconducting transport mechanism.
DETAIL FOR DOCTOR RESEARCH
Thermoelectric technology is a kind of conversion technology between heat and electricity.
Bi2Te3-based and CoSb3-based alloys are mainly applied in thermoelectric devices because
they are known as the best TE materials near room temperature. The purpose of my research
is to improve the TE and mechanical properties of Bi2Te3-based and CoSb3-based alloys.
