Cross-plane Seebeck coefficient of ErAs:InGaAs/InGaAlAs superlattices [link]Paper  abstract   bibtex   
We characterize cross-plane and in-plane Seebeck coefficients for Er As : In Ga As / In Ga Al As superlattices with different carrier concentrations using test patterns integrated with microheaters. The microheater creates a local temperature difference, and the cross-plane Seebeck coefficients of the superlattices are determined by a combination of experimental measurements and finite element simulations. The cross-plane Seebeck coefficients are compared to the in-plane Seebeck coefficients and a significant increase in the cross-plane Seebeck coefficient over the in-plane Seebeck coefficient is observed. Differences between cross-plane and in-plane Seebeck coefficients decrease as the carrier concentration increases, which is indicative of heterostructurethermionic emission in the cross-plane direction.
