摘要：

Plasmons in the terahertz (THz) range have been observed in Bi2Se3 topological insulator films patterned in form of micro-structures. These plasmons have been assigned to collective excitations of massless Dirac carriers located onto the Bi2Se3 topological surfaces. Their lifetime is mainly determined by the single-particle scattering rate and results scarcely dependent on temperature as expected for topological carriers.
