Abstract
The variation of thermopower with temperature from 77 to 300 K has been measured in samples of nanostructured silver. It is observed that a dramatic change occurs in the thermopower of the nanostructured silver as grain size is reduced into the nanoscale region. In particular, with the grain size decreasing to the nanometer scale, the slope of the electron-diffusion component of thermopower as a function of temperature increases and the phonon-drag component of thermopower is shifted to lower temperatures. The changes in the thermopower correlate well with changes in the microhardness.
