Properties of Cu-intercalated TaSe2

TaSe2 belongs to a group of materials named transition metal dichalcogenides, exhibiting various interesting spin and transport properties. The layered nature of TaSe2 allows for intercalation, which introduces elements such as electrons, holes, or magnetic moments to the system. The superconductivity of TaSe2 is enhanced by nickel intercalation, the origin of which is not well-understood. To contrast with magnetic intercalation, Cu-intercalated samples are synthesized. The experimental synthesis methods and findings on Cu-intercalated samples will be discussed in the context of recent evidence of enhanced superconductivity with Ni-intercalation of this material.
