Query: Tunable terahertz plasmons in graphite thin films   Tunable terahertz plasmons are essential for reconfigurable photonics, which
have been demonstrated in graphene through gating, though with relatively weak
responses. Here, we demonstrate strong terahertz plasmons in graphite thin
films via infrared spectroscopy, with dramatic tunability by even a moderate
temperature change or an in-situ bias voltage. Meanwhile, through
magneto-plasmon studies, we reveal that massive electrons and massless Dirac
holes make comparable contributions to the plasmon response. Our study not only
sets up a platform for further exploration of two-component plasmas, but also
opens an avenue for terahertz modulation through electrical bias or all-optical
means.
