Abstract

The deep subwavelength confinement of infrared light offers exciting opportunities to manipulate photons, engineer thermal energy transport, and enhance molecular reactivity. Applications leveraging these phenomena will require constituent materials and devices that not only exhibit precisely controlled structural and compositional heterogeneity, but also can be produced at very large scales. Purely top-down fabrication techniques are unlikely to succeed in both regards. The bottom-up vapor-liquid-solid (VLS) mechanism – whereby a liquid seed particle collects precursor molecules from the vapor and directs crystallization of a nanowire – promises the requisite nanoscale programming of structure and composition while simultaneously being amenable to high-throughput manufacturing. This talk will describe our recent efforts to synthesize, understand, and engineer the infrared plasmonic properties of VLS-grown semiconductor nanowires. In particular, I will discuss (i) how programming of dopant profile along the nanowire length enables designer infrared spectral responses, (ii) that combining the dielectric properties of semiconductors and the 1-D geometry of nanowires leads to very strong near-field interactions, and (iii) that these interactions promise the efficient waveguiding of light and heat.
