“…Any systematic trends in QZ between bcc and fcc hosts must come from S and not from the differences in Fa mentioned in 5 1.3. The fact that the thermopower similarly contains no terms in the activation energy has been widely acknowledged: this arises from the fact that the interstitial properties contain no significant contributions from the band like states (Sewell 1963, Schotte 1967, Efros 1967, Klinger 1968, Austin and Mott 1969.…”

Abstract. The electromigration and thermomigration of light interstitials, such as hydrogen in metals, have been examined in terms of the quantum theory of diffusion of Flynn and Stoneham. The pronounced isotope effect observed in the effective charge 2 is shown to come from the differences in the self trapping distortions of the various isotopes. The qualitative dependence of Z* on isotope, host lattice and temperature are correctly predicted.The interstitial contribution to the reduced heat of transport Q* is calculated directly from the quantum theory. There is no term proportional to the activation free energy in the regime of interest. The dominant contribution to Q* is probably that from the electron gas, although the entropy of solution adds an important term. Again, the qualitative results are consistent with the sparse experimental data.

X theory is developed for a polarization mechanism of absorption of electromagnetic waves by polarons localized on impurity centres with an appropriate structure. The coefficient of this absorption shows a specific frequency (o) dependence both a t low and at high w and some basic features (at high o) similar to those for the high-frequency conductivity for small polarons and for the well-known resonance impurity polaron absorption.

The essential question whether such description is adequate for the hopping impurity conduction will be discussed separately elsewhere (cf. [14, 171): for (nearly) resonance impurity pairs ( z = 2), the theory presented here is adequate. 34 pliysica 31/2

“…8 In this case, the electronic conduction is reported in the literature to be a thermally activated small polaron hopping [3,4,7]. The electronic conductivity is due to the relatively small distances between the iron ions and the existing localization of the states [1,2,7,9,10]. Eq.…”
