Record-High Thermoelectric Performance in Al-Doped ZnO via Anderson Localization of Band Edge States. [PDF]

Adv Sci (Weinh)
This study reports on the thermoelectric properties of Al‐doped ZnO ceramics, synthesized via chemical co‐precipitation at strongly alkaline conditions. A large enhancement of the thermoelectric performance (zT = 0.5) is obtained and attributed to disorder‐induced modifications of the electronic structure, namely Anderson localization of band edge ...
