Doping of metal into transition metal dichalcogenides PdTe₂

Abstract Rh-doped PdTe2 single crystals were successfully prepared using the solid-state reaction. The change of lattice constants and T c with increasing Rh content were studied and investigated. It was found that there is a very slight increase of lattice constant c with increasing Rh content. The values of T c were above 2 K when Rh content is equal to 0.05 and 0.1. The largest T c was~2.7 K for Rh0.05PdTe2 single crystal. T c does not increase with increasing x from 0.05 to 0.1. M-T measurement of Rh0.05PdTe2 single crystal with applied magnetic field H perpendicular to the c axis and along and c axis gives evidence of type II superconducting behavior. This study shows Rh doping is a promising method to increase T c and investigate SC in PdTe2.
