The effects of charge carriers, organic solvents and magnetic ions on the superconductivity of doped 1T-SnSe<sub>2</sub>

ORAL

Abstract

We reported bulk superconductivity up to 7.6 K through careful manipulation of the charge carrier density and basal spacing d in the chemically intercalated two dimensional CdI2-type 1T-SnSe2 phase. We found out the very unusual scaling behaviour of Tc with the basal spacing distance caused by different organic co-intercalation, meanwhile the Tc appears to be almost independent with the alkali metal concentration. In this presentation, we focus on more chemical doping studies that close to the insulator-superconducting transition regime, more precisely-controlled doping level and various organic molecules have been tested through soft chemical methods. In addition, intercalation of the magnetic molecules are also carried out to study the interplay of superconductivity, magnetism, and possible charge density wave transition in these intercalated system. The details of the results will be presented with their physics origins being further elaborated.
