Quantum Theory of Conducting Matter

The measurements of the Hall coe?cient R and the Seebeck coe?cient H (thermopower) S are known to give the sign of the carrier charge q. Sodium (Na) forms a body-centered cubic (BCC) lattice, where both R and S are H negative, indicating that the carrier is the "e;electron. "e; Silver (Ag) forms a face-centered cubic (FCC) lattice, where the Hall coe?cient R is negative H but the Seebeck coe?cient S is positive. This complication arises from the Fermi surface of the metal. The "e;electrons"e; and the "e;holes"e; play important roles in conducting matter physics. The "e;electron"e; ("e;hole"e;), which by de?- tion circulates counterclockwise (clockwise) around the magnetic ?eld (?ux) vector B cannot be discussed based on the prevailing equation of motion in the electron dynamics: dk/dt = q(E +v B), where k = k-vector, E = electric ?eld, and v = velocity. The energy-momentum relation is not incorporated in this equation. In this book we shall derive Newtonian equations of motion with a s- metric mass tensor. We diagonalize this tensor by introducing the principal masses and the principal axes of the inverse-mass tensor associated with the Fermi surface. Using these equations, we demonstrate that the "e;electrons"e; ("e;holes"e;) are generated, depending on the curvature sign of the Fermi s- face. The complicated Fermi surface of Ag can generate "e;electrons"e; and "e;holes,"e; and it is responsible for the observed negative Hall coe?cient R H and positive Seebeck coe?cient S.
