SEM/TEM of the Month.(Industry Watch)(Nanoforest)(Metal-Organic Vapor-phase Epitex)(Brief Article)

Semiconductor International, July, 2004 by Singer, Peter

This nanoforest was produced from GaP, by a sequential-seeding process. As noted by Kimberly Dick, a student in the Solid State Physics department at Lund University (Lund, Sweden), the tree trunks were grown epitaxially in MOVPE in the [111]B direction on GaP (111)B substrates; the nanowires were seeded by gold nanoparticles produced by electron-beam lithography in an array pattern. To produce the branches, gold aerosol nanoparticles were deposited onto the trunks; second-generation nanowires were then grown in MOVPE in the other three symmetry-related B directions. The image was taken at 12,000x magnification.
