"Seebeck effect laid the foundation of the field of thermoelectrics, which deals with materials producing electricity under the application of a temperature difference... Similar to the concept of an electrical conductivity, thermoelectricity is governed by the Peltier conductivity... stemmed from a low residual resistivity... was caused by the high mobility, low concentration, and heavy mass of the holes inside the crystal... [could enable] compact, low-cost MRI machine, making medical diagnosis more convenient"
