Originating Calendar
Physics - Condensed Matter Seminar

Ever since their discovery, superconductivity in cuprates has motivated the search for materials with analogous electronic or atomic structure. Here we present how soft chemistry approaches can be used to synthesize superconducting infinite layer nickelates from their perovskite precursor phase, using topotactic reactions. We present our finding of a doping dependent superconducting dome in (Nd,Sr)NiO2, a common feature in many unconventional superconductors. We will discuss our current understanding of aspects of the electronic structure, including the unusual role of Nd hybridization.
