Abstract:
1. A method of forming a nanostructure, comprising: a first stage which includes providing at least one first catalytic particle on a substrate surface, and growing a first nanowhisker by a VLS process via each first catalytic particle; and a second stage which includes depositing on a peripheral surface of at least one said first nanowhisker at least one second catalytic particle, and growing, by a VLS process from each second catalytic particle, a second nanowhisker extending transversely from the peripheral surface of the respective first nanowhisker, wherein said providing comprises forming an aerosol flow comprising said first catalytic particles and depositing a plurality of said first catalytic particles from the aerosol flow on the substrate surface.
