PdCoO2 layered delafossite is the most conductive compound among metallic oxides, with a room-temperature resistivity of nearly $$2\,\mu \Omega \,{{{{{\rm{cm}}}}}}$$ 2 μ Ω cm , corresponding to a mean free path of about 600 Å. These values represe

STM imaging of strongly correlated materials with spin-orbit coupling

Autor: Chakraborti, Dibyashree

Most of the properties of electrons in conducting materials that we encounter in our everyday lives can be explained very neatly by considering them to be independent entities residing in the crystal lattice potential, as described by band theory of

The rational design of catalysts is crucial to make power-to-X technologies viable. Here the authors introduce the delafossite PdCoO2 as a highly active hydrogen evolution reaction catalyst due to the growth of a tensile-strained Pd-rich capping laye
