We synthesized single crystals of β-MoTe2 by the chemical vapor transport (CVT) method. Resistivity and magnetoresistivity (MR) have been measured. The MR displays H2 behavior at low field and linear field dependence at high field, which is different from the quadratic behavior in the sample obtained from the NaCl-flux method. It is suggested that the observed linear MR may originate from disorder. The quality and low-temperature property of β-MoTe2 clearly depend on the growth method. Moreover, the angular-dependent MR reveals the two-fold symmetry of Fermi surface.
