Why does Bismuth have a anomalously high Hall value?

  1. May 17, 2014 #1
    Bismuth has a hall coefficient 1000 times larger than its free electron value. given that Bi has a distorted cubic structure with 2 atoms per unit cell, suggest a reason for the high hall value.

    Any ideas appreciated. Thanks.

    For the benefit of the OP and anyone else, Bismuth is not a monovalent element and so the simple formulas for the Hall effect based on the free-electron model and applicable to monovalent conductors are not valid for multi-valent conductors. Quantum mechanics gives approximately correct answers.
