description | <p>Abstract</p> <p>The long-term (6 months) oxidization of hcp-InN (wurtzite, InN-w) nanostructures (crystalline/amorphous) synthesized on Si [100] substrates is analyzed. The densely packed layers of InN-w nanostructures (5-40 nm) are shown to be oxidized by atmospheric oxygen via the formation of an intermediate amorphous In-O<sub> <it>x</it> </sub>-N<sub> <it>y </it> </sub>(indium oxynitride) phase to a final bi-phase hcp-InN/bcc-In<sub>2</sub>O<sub>3 </sub>nanotexture. High-resolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, electron energy loss spectroscopy and selected area electron diffraction are used to identify amorphous In-O<sub> <it>x</it> </sub>-N<sub> <it>y </it> </sub>oxynitride phase. When the oxidized area exceeds the critical size of 5 nm, the amorphous In-O<sub> <it>x</it> </sub>-N<sub> <it>y </it> </sub>phase eventually undergoes phase transition via a slow chemical reaction of atomic oxygen with the indium atoms, forming a single bcc In<sub>2</sub>O<sub>3 </sub>phase.</p> |
