Abstract

We fabricated a unique system in which a semiconductor nanowire and a gold bowtie nanoantenna are combined. InP nanowire is precisely placed in the nanogap of the nanoantenna with a nanomanipulator installed in a focused ion beam system. By measuring the intensity mapping of the photoluminescence from the nanowire, we observed a significantly large enhancement at the antenna gap. We also calculated the electric field numerically, and the simulated results showed that the large enhancement that is obtained was caused by plasmonic resonance and was affected by the breakdown of the field suppression effect in the subwavelength nanowire.
