| Outline of Final Research Achievements |
Unusual electron thermal conductivity was realized by use of fine electronic structure in the energy range of a few kBT centered at the chemical potential. With employing the condition of small lattice thermal conductivity, we obtained materials possessing the unusual heavier of electron thermal conductivity. We also construct thermal diodes using such materials of unusual electron thermal conductivity with additionally employing materials possessing thermal conductivity moderately varying with temperature due to the lattice contributions.
