  We report that the isovalent Rh doping of IrTe2 suppresses the
structural/electronic phase transition and induces superconductivity at 2.6 K.
The doping level of Rh that is necessary for suppressing the transition is
three times higher than those of Pt and Pd. Ir1-xRhxTe2 might provide us with a
unique opportunity to study the origin of the structural/electronic phase
transition in IrTe2.
