Abstract
A series of samples is not required to derive the parameters needed for an SPB model; indeed, it only takes data for a single sample. However, this modeling is best performed when a series of samples are available, as this allows the accuracy of the model to be tested. It is common for only a sample or two to be available, though, and in these cases the SPB model can suggest avenues to enhance the thermoelectric effciency, such as increasing or decreasing the carrier density, and give a prediction for zT in an optimized sample. Alternatively, a model developed for a novel compound may suggest that a large figure of merit zT is not achievable in the system without the introduction (or possibly the discovery) of irregular features in the transport properties. Thus, the SPB model is something of a diagnostic tool for both overall thermoelectric effciency and the existence of more complex transport behavior.
