Excitation laser energy dependence of the gap-mode TERS spectra of WS${}_2$ and MoS${}_2$ on silver

Andrey Krayev, Eleonora Isotta, Lauren Hoang +8

We present a systematic study of the dependence of gap mode tip-enhanced Raman scattering (TERS) of mono- and bi-layer WS${}_2$ and MoS${}_2$ as a function of excitation laser energy.…
