The synthesis of self-assembled In2O3 nanocrystal chains and networks (see Figure) on SiO2-covered Si substrates by a thermal evaporation and condensation method is reported. Au catalyst is required for the growth. The chains and networks can be used for the fabrication of complex nanoelectronic devices and toward a better understanding of nanodevice physics.
