Stepwise Vacancy Manipulation for Optimized Carrier Concentration and Blocked Phonon Transport Realizing Record High Figure of Merit <i>zT</i> in CuInTe<sub>2</sub> Open
Great enhancement in the thermoelectric performance of CuInTe 2 is achieved through stepwise regulation of Cu vacancies. Lowering Cu content can effective introduce large number of Cu vacancies, which is substantiated by positron annihilat…
