Epitaxial GaN nanorods on GaN substrate

  GaN nanobrushes in the (a) medium magnification showing presence of 2- and 4-fold nanostructures and high magnification (b) 4S-fold, (c) 4M-fold , (d) 4M*1-fold (e) 2S-fold subsymmetries.

    Temperature dependent PL spectra of the black InN nanorods measured at (a) 20 K, (b) 60 K, (c) 100K and (d) 140 K. The dashed line labels the peak position of 0.766 eV obtained at 20 K. The inset shows the PL spectrum from the optically brown InN nanorods measured at RT using the micro PL setup (Renishaw 2000).
