ELECTRON AND PHONON SCATTERING. II. THERMOELECTRICITY IN RUBIDIUM, CAESIUM AND ALLOYS AT VERY LOW TEMPERATURES
Following earlier measurements on pure potassium and alloys, a corresponding study at very low temperatures of thermoelectricity in rubidium, cesium, and their alloys with each other and with potassium was made. The results proved in accord with the interpretation of the earlier work, and the trends observed in both the electron diffusion and phonon-drag contributions to the absolute thermoelectric power are discussed. Both contributions as observed in these metals are consistent with a larger distortion in the Fermi surface of cesium than in those of potassium or rubidium. It appears that the changes in the thermoelectric diffusion term can be attributed consistently to the difference arising from large-angle and small-angle scattering. It is supposed that in turn these types of electron scattering arise from the presence of homovalent and heterovalent impurity centers. (auth)
