Hall Mobility in n-Type Molybdenum Ditelluride

Abstract

The temperature dependence of the electron mobility in molybdenum ditelluride single crystals has been measured in the temperature range between 8 K and 830 K. The results are examined with the three dimensional Schmid’s model and two dimensional Fivaz’s model for homopolar optical phonon scattering. The temperature dependence in high temperature region above about 350 K is well explained by Schmid’s model.
The resistivity anisotropy ρ_⁄⁄c⁄ρ_⊥c is also presented.
