Takahashi, Masamitsu; Kozu, Miwa*; Hu, W.*; Nakata, Yuka

The polytypism of GaAs nanowires was investigated by in situ X-ray diffraction. The growth of nanowries was found to start with the formation of zincblende structure, followed by the growth of the wurtzite structure. Comparison with the simulation based on the thermodynamic model of nucleation shows that the observed transition of the growth mode is due to the increase in supersaturation during nanowire growth.
