Record‐High Thermoelectric Performance in Al‐Doped ZnO via Anderson Localization of Band Edge States
Advanced Science, Volume 11, Issue 26, July 10, 2024.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 ...

INTRINSIC DEFECTS IN ZnO VARISTOR CERAMICS
Acta Physica Sinica, 1996 The relationship between dielectric loss factor D (tanδ) and frequency for ZnO-Sb2O3-BaO and ZnO-Bi2O3-Sb2O3-BaO varistor ceramics has been investigated. A new dielectric loss peak was found near by 2MHz at room temperature for the sample in the absence of Bi2O3, the corresponding electron trapping level was about 0.18 eV, it was considered that the ...
