FIG. 1.

(Color online) (a) Molecular structure of TPP. (b) Schematic junction geometry with multi-monolayer stacking and localized electrical excitation by a plasmonic tip. (c) and (d) are STM images of 1-ML TPP on HOPG (+2.0 V, 20 pA, 15 × 15 nm2) and 5-ML TPP on HOPG via layer-by-layer growth (+2.6 V, 20 pA, 15 × 15 nm2).

FIG. 2.

(Color online) (a) Featureless STML spectra obtained on HOPG using a W-tip (±2.5 V, 0.4 nA, 600 s). The bottom spectral curve shows the plasmonically “bright” tip status of the same tip on Ag(111) (+2.5, 0.4 nA, 60 s). The inset is an atomically resolved STM topograph of HOPG (+0.5 V, 0.3 nA, 2 × 2 nm2). (b) Bias polarity dependence of STML spectra acquired above 5-ML TPP on HOPG (±2.5 V, 0.4 nA, 600 s). The PL spectrum measured in situ is also shown as a comparison. (c) Bias dependence of STML spectra acquired at different sample bias showing an onset voltage around 2.2 V (0.4 nA, 600 s).

FIG. 3.

(Color online) (a) and (b) Dashed curves: STML spectra showing the tip plasmon modes on Ag(111) with a W-tip (+2.5 V, 0.4 nA, 60 s); Solid curves: Corresponding STML spectra obtained above 5 ML TPP on HOPG using the same tip with pre-tuned plasmon modes (+2.8 V, 0.4 nA, 600 s). (c) Schematic diagram of two possible excitation processes for the generation of molecular electroluminescence.
