Abstract

Lithium intercalation and de-intercalation processes have been used to fabricate bulk Bi_(2)Se_(0.3)Te_(2.7) with internal nanostructures. The doped Li content can be precisely controlled through this method. It provides a chance to directly optimize electrical properties when preparing nano-structured materials, leading to the optimum carrier concentration for improved thermoelectric figure of merit.
