Abstract

Nanoscale plasmonic phenomena observed in single and bi-layers of molybdenum disulfide (MoS<sub>2</sub>) on silicon dioxide (SiO<sub>2</sub>) are reported. A scattering type scanning near-field optical microscope (s-SNOM) with a broadband synchrotron radiation (SR) infrared source was used. We also present complementary optical mapping using tunable CO<sub>2</sub>-laser radiation. Specifically, there is a correlation of the topography of well-defined MoS<sub>2</sub> islands grown by chemical vapor deposition, as determined by atomic force microscopy, with the infrared (IR) signature of MoS<sub>2</sub>. The influence of MoS<sub>2</sub> islands on the SiO<sub>2</sub> phonon resonance is discussed. The results reveal the plasmonic character of the MoS<sub>2</sub> structures and their interaction with the SiO<sub>2</sub> phonons leading to an enhancement of the hybridized surface plasmon-phonon mode. A theoretical analysis shows that, in the case of monolayer islands, the coupling of the MoS<sub>2</sub> optical plasmon mode to the SiO<sub>2</sub> surface phonons does not affect the infrared spectrum significantly. For two-layer MoS<sub>2</sub>, the coupling of the extra inter-plane acoustic plasmon mode with the SiO<sub>2</sub> sur...Continue Reading
