Low Temperature Thermoelectric Characterization of Ag$_{\mathrm{2}}$Se.*

Previous work on Ag$_{\mathrm{2}}$Se showed that this n-type material could have a dimensionless thermoelectric figure of merit (zT) \textasciitilde 1 at room temperature, due to its high mobility and low thermal conductivity. However, the results from the initial reports have not yet been reproduced. In this talk, I will summarize our efforts to replicate the aforementioned thermoelectric performance, and also discuss the experimental setup that we utilized in order to perform the low-temperature thermoelectric characterization of this material.
