TRANSIENT THERMOELECTRIC EFFECT OF BISMUTH CRYSTAL UNDER STATIC MAGNETIC-FIELD

For an extension of a dynamic technique, called the photo-induced ''tr ansient thermoelectric effect (TTE),'' to study multicarrier transport in various solids, we have studied the effect of static magnetic fiel ds on the TTE for bismuth crystals as a test sample. The TTE signals u nder magnetic fields show an asymmetric behavior for the reversal of t he magnetic field direction. The analysis of TTE decay curves gives mu ltiple relaxation times corresponding to different types of electrons, which show anomalous magnetic field dependence.
