摘要

Thermal decomposition of Lewis acid-base adducts [t-Bu_3Ga-Sbi-Pr_3] (1) and [t-Bu_3Ga]_2[Sb_2Et_4] (2) in closed glass ampoules at temperatures between 250 and 350 ℃ yielded crystalline GaSb nanowires. Isolated GaSb nanowires were formed preferably at low decomposition temperatures, whereas dendritic-like growth was observed at higher decomposition temperatures. In addition, self-catalyzed growth of GaSb nanowires using 90nm-sized Ga droplets, which were pre-deposited on Si(100) substrates, was achieved with the distibine Sb_2Et_4 at 250℃.
