Researchers realize remote tuning of lifetime of coupled Dirac plasmons

Recently, the team led by Prof. Zeng Changgan from the University of Sciences and Technology of China (USTC) of the Chinese Academy of Sciences, collaborating with Li Xiaoguang's team from Shenzhen University, has enabled the remote tuning of the lifetime of coupled plasmon excitations by designing and introducing an additional damping pathway through adjusting the Fermi energy level of graphene, and the damping tuning system has been elucidated in conjunction with theory. The study was publishe...
