The physics of electrons, photons and their plasmonic interactions changes greatly when
one or more dimensions are reduced down to the nanometre scale. For example, graphene …

Plasmonic transdimensional materials (TDMs), which are atomically thin metals of precisely
controlled thickness, are expected to exhibit large tailorability and dynamic tunability of their …

Overcoming the challenge of growing ultrathin metallic films is of great importance for
practical applications of nanoplasmonic structures. In the present work, epitaxial, ultrathin (< …

The main aim of this study is to scrutinize promising plasmonic materials by understanding
