Researchers at the University of California at San Diego (UCSD) are the first to have used infrared nano-imaging to study how surface plasmons (collective oscillations of electrons) propagate in “moiré-patterned” graphene grown on hexagonal boron nitride. The observations, which reveal new collective plasmon modes, could help in the development of advanced plasmonic circuits for novel tunable optical and optoelectronic devices…..
