Tunneling-current-induced local excitonic luminescence in p-doped WSe monolayers
Ricardo Javier Peña Román, Yves Auad, Lucas Grasso +3
We have studied the excitonic properties of exfoliated tungsten diselenide (WSe) monolayers transferred to gold substrates using the tunneling current in a Scanning Tunneling M…

Group velocity modulation and wavelength tuning of phonon-polaritons by engineering dielectric-metallic substrates
Flávio H. Feres, Rafael A. Mayer, Ingrid D. Barcelos +2
In analogy to the observed for single plasmon-polaritons, we show that subdiffractional hyperbolic phonon-polariton (HP2) modes confined in hexagonal boron nitride (hBN) nanocrysta…
