Germanium-catalyzed hierarchical Al2O3 and SiO2 nanowire bunch arrays
Zhanjun Gu, Feng Liu, Jane Y. Howe, M. Parans Paranthaman and Zhengwei Pan,
Nanoscale, 2009, 1, 347
DOI: 10.1039/b9nr00040b Enhanced HTML article available
Germanium is an effective catalyst for the growth of highly aligned, closely packed polycrystalline Al2O3 and amorphous SiO2 nanowire bunches. The Ge-catalyzed nanowire growth exhibits interesting growth behavior not observed in conventional Au-catalyzed nanowire growth.
