Strong Confinment of optical fields using localised surface phonon polaritons in cubic Boron Nitride
Ioannis Chatzakis, Athith Krishna, James Culbertson +4
Phonon polaritons (PhPs) are long-lived electromagnetic modes that originate from the coupling of infrared photons with the bound ionic lattice of a polar crystal. Cubic-Boron nitr…
Broadband Terahertz Modulation in Electrostatically-doped Artificial Trilayer Graphene
Ioannis Chatzakis, Zhen Li, Alex Benderskii +1
We report a terahertz optical modulator consisting of randomly stacked trilayer graphene (TLG) deposited on an oxidized silicon substrate by means of THz- Time Domain Spectroscopy…
Temperature dependence of the anharmonic decay of optical phonons in carbon nanotubes and graphite
Ioannis Chatzakis, Hugen Yan, Daohua Song +2
We report on the temperature dependence of the anharmonic decay rate of zone-center (G mode) optical phonons in both single-walled carbon nanotubes and graphite. The measurements a…
