Nuclear Magnetic Resonance in Lead Telluride
Author: Charles Robert Hewes

ISBN:
Category : Lead compounds
Languages : en
Pages : 220
Book Description
Nuclear magnetic resonance (NMR) measurements have been used to develop a detailed model of the energy band structure of PbTe in the vicinity of the valence and conduction band edges. In addition, the hyperfine couplings between the carrier states and the Pb207 and Te125 nuclei have been determined. A parameterized k.pi nonparabolic model for the valence band conduction bands has been developed which takes account of the k.pi couplings among the six bands near the Fermi level at the L point of the Brillouin zone. From this band model, expressions are developed for the Fermi energy dependence of the g factors, the nonparabolic density of states, and the carrier concentration and temperature dependence of the Knight shift. The hyperfine coupling between the Pb207 nuclei band the valence band states is found to be nearly equal to the coupling between the Pb207 nuclei and the conduction band states. Both hyperfine constants are more than an order of magnitude larger than the hyperfine constant of the Pb(6s) state for neutral atomic lead. Relativistic corrections are examined to account for the unusual magnitudes of both hyperfine constants. The Pb207 resonance lineshape and resonance position were used to observe a damaged-induced compensation effect in p-type PbTe, which was not observed in n-type material. (Author).
