Abstract:
1. A method for forming at least one doped elongated nanostructure on a substrate, the method consisting of: providing a gaseous source of nanostructure material; providing at least one catalyst particle on a substrate, the catalyst particle consisting of a catalyst compound and at least one dopant element, wherein the catalyst compound comprises at least one catalyst element, and wherein the catalyst element and the dopant element are different elements; and thereafter growing at least one elongated nanostructure comprising the nanostructure material between the catalyst particle and the substrate, wherein the catalyst compound catalyzes growth of the elongated nanostructure without substantially dissolving in the nanostructure material, wherein the dopant element dopes the elongated nanostructure during growth by substantially completely dissolving in the nanostructure material, wherein a dopant element concentration in the doped elongated nanostructure is lower than 10
