Possible Rashba band splitting and thermoelectric properties in CuI-doped Bi2Te2.7Se0.3 bulk crystals

We investigated thermoelectric properties of the CuI-doped (CuI)xBi2Te2.7Se0.3 bulk crystals grown by the Bridgman method. From the formation energy calculation and lattice parameter expansion along the c-axis, we confirm that the Cu-atom intercalates at the van der Waals layer while iodine substitu...
