ResumoIndium nitride micro- and nanostructures have been prepared by the reaction of indium oxide and ammonia in the temperature range 600–730 °C. Depending on the reaction temperature, nanoparticles with a diameter of 50–100 nm, nanowires with a diameter of ∼100 nm and of varying length, hollow microtubes or two-dimensional microplates were formed, as observed by transmission electron microscopy and scanning electron microscopy. The microscopy data are consistent with the transformation from one morphology to another by means of a vapor–solid transport mechanism. All crystals possess the wurtzite structure, independent of their morphology.
