Abstract

Here in this short note, we report on the low dimensional 4d and 5d transition metals-chalcogenide based compounds i.e., Ta2PdxS6, showing semiconducting to superconducting transition around 4K with upper critical field outside Pauli paramagnetic limit. It seems couple of different superconducting phases do exist in these new set of compounds. Our short note in this regards is thought provoking, asking to explore various unearthed possible superconducting phases in (Nb/Ta)2Pdx(S/Se/Te)y systems.
