Abstract

The layered transition metal chalcogenides have been a fertile land in solid state physics for many decades. Various MX₂-type transition metal dichalcogenides, such as WTe₂, IrTe₂, and MoS₂, have triggered great attention recently, either for the discovery of novel phenomena or some extreme or exotic physical properties, or for their potential applications. PdTe₂ is a superconductor in the class of transition metal dichalcogenides, and superconductivity is enhanced in its Cu-intercalated form, Cu_0.05PdTe₂. It is important to study the electronic structures of PdTe₂ and its intercalated form in order to explore for new phenomena and physical properties and understand the related superconductivity enhancement mechanism. Here we report systematic high resolution angle-resolved photoemission (ARPES) studies on PdTe₂ and Cu_0.05PdTe₂ single crystals, combined with the band structure calculations. We present in detail for the first time the complex multi-band Fermi surface topology and densely-arranged band structure of these compounds. By carefully examining the electronic structures of the two systems, we find that Cu-intercalation in PdTe₂ results in electron-doping, which causes the band structure to shift downwards by nearly 16 meV in Cu_0.05PdTe₂. Our results lay a foundation for further exploration and investigation on PdTe₂ and related superconductors.
