Effect of severe plastic deformation on thermoelectric properties of BiCuSeO
High-pressure torsion is used to attain grain refinement and introduce dense dislocations in BiCuSeO. The effect of HPT reduces the bandgap, increases carrier concentration and reduces κ to improve thermoelectric performance of BiCuSeO.
