Modulation of Semiconductor Superlattice Thermopower Through Symmetry and Strain
Vitaly. S. Proshchenko, Manoj Settipalli, Artem K. Pimachev +1
In doped semiconductors and metals, the thermopower decreases with increasing carrier concentration, in agreement with the Pisarenko relation. Here, we demonstrate a new strain eng…
