Abstract

Read online

Coherent acoustic plasmons in time-domain measurements are rarely observed due to Landau damping. Here, Glinka et al. use transient second-harmonic generation to observe coherent acoustic Dirac plasmon modes survived in indirectly opposite-surface coupled Bi2Se3films due to Dirac fermion tunnelling.
