Evidence of Charge density wave in Re doped MoTe<sub>2</sub>
ORAL
Abstract
Transition metal dichalcogenides exhibit interesting structural and intercalation chemistry and consequent exotic physical properties. Superconductivity with a very low transition temperature of 0.1 K was earlier discovered in the orthorhombic MoTe2. MoTe2 also shows a charge density wave (CDW) phase when grown in thin film form, but a CDW phase in bulk MoTe2 has not been reported. It is also known that Re substitution for Mo sites leads to an increase in superconducting transition temperature. Mo0.8Re0.2Te2 shows a high critical temperature Tc of 3.8 K. Based on our transport and scanning tunneling microscopy experiments we will discuss that the compound Mo0.8Re0.2Te2 also supports a CDW phase with an onset temperature of 150 K. Our results suggest that CDW and superconductivity may compete with each other in Re doped MoTe2.
