Experimental Results and Simulation (IMAGE)
Caption
(a) SEM images of a gold FIB-tip. A single groove is made at a distance (L) from the apex.
(b) Schematic of STL measurement. Light emission (hv) occurs through excitation of LSPR in the junction by tunneling electrons (e-).
(c) STL spectra obtained by FIB-tips. Spectral modulation is observed for the tips with a groove and the oscillation period depends on the groove distance.
(d) Electrodynamic simulations of two-dimensional electric field mapping for the FIB-tip with a groove. Standing formation of SPP occurs on the tip shaft.
