| Summary: | The formation and evolution mechanisms of plasmon resonance from single Ring-shaped nanotube to dimer and arrays are studied; an attempt has been made to bridge the gap between single-tube, dimer, and array. Results show that resonant modes can be divided into three types: quadrupole, hexapole, and octupole resonance from visible to near infrared region, and each mode maintains relatively stable resonant characteristics, but the optical transmission properties including redshift and blueshift of the modes and band gap are highly tunable by adjusting the number of nanotube and intertube spacing values. The field-interference mechanism has been suggested to explain the physical origin. |
