“…Coupling with different material systems and (quasi‐) particles therein, might result not only in field enhancement but in new quasiparticles such as chiral plasmons [ 76 ] and plexcitons. [ 77,78 ] Strong light matter interaction in the non‐linear [ 79 ] as well as linear regime with ENZ properties found for these 2D polar metals is expected to result in fascinating and unprecedented phenomena facilitated by the unique properties of the 2D metals and their expected high tunability and integrability in photonic, plasmonic, and optoelectronic circuitries for next generation photonics, quantum plasmonics, hot‐electron generation, photo‐catalysis, solar power harvesting, sensing, and nano‐particle trapping.
