• appearance of localized “hot spots”. In particular, semiconducting nanostructures can sustain Mie-like leaky modes due to their high refractive index and the occurrence of multiple internal light reflections from the boundaries of the structure [9][13]. However, in vertical nanowires under normal-incidence

• solely interested in demonstrating the difference and contrast for different frequencies, so we have chosen two convenient emission lines of our laser. The correspondence between patterns of nanogaps, localized hot spots and polarization can be described by invoking the idea that the nanogaps are

• represented in Figure 4. Another critical factor that affects the localized hot spots is the polarization [13]. Since the plasmon resonance depends on the restoring force resulting from a noncompensated surface charge, this force depends ultimately on the shape of the topography profile and polarization, i.e
