Cover Story: Nanoscale geometries possess unique thermal properties that geometrically limit heat dissipation to underlying substrates, which is a commonly observed phenomenon in electron- and ion-beam-induced deposition. Here, we leverage these thermal properties by using a pulsed laser source to heat and induce thermal CVD reactions selectively on nanostructures. The process is shown to not be limited to a particular substrate, but is rather controlled by a combination of precursor flux, laser conditions, and the optical and thermal properties of the nanostructure. High-purity (>95 atomic %) gold deposition consistent with large-scale thermal CVD results is reported in this special edition of Nanomaterials. View this paper
