Influence of defects on the enhancement of thermoelectric properties in Sn-doped ZnO nanostructure synthesized via hydrothermal route.

In this study, a clear trend of increasing oxygen vacancies with higher Sn doping concentrations was observed and these defects are primarily for the enhancement of thermoelectric efficiency as discussed in the next section. 3.5 Thermoelectric properties To investigate the thermoelectric properties, the nanopowder samples were compacted into circular pellets under a pressure of 10 tons for 1 minute.
