Growth of mono-dispersed AlGaN nanowires of ternary wurtzite phase is reported using chemical vapour deposition technique in the vapour-liquid-solid process. The role of distribution of Au catalyst nanoparticles on the size and the shape of AlGaN nanowires are discussed. These variations in the morphology of the nanowires are understood invoking Ostwald ripening of Au catalyst nanoparticles at high temperature followed by the effect of single and multi-prong growth mechanism. Energy-filtered… 


Polarization-sensitive optical phenomena in semiconducting and metallic nanowires
An analysis is presented of optical absorption and emission in semiconducting, metallic, and mixed core-shell nanowires are considered theoretically. Due to image forces caused by the difference in

For semiconducting nanowires with the dielectric constant e differing from that of their environment, the distribution of ac electric fields, created in a nanowire by an external lightwave and
Multiphonon Raman Spectrum of Silicon
The energy and polarization characteristics of the one- and two-phonon Raman spectrum have been measured using a 180\ifmmode^\circ\else\textdegree\fi{} backscattering technique. The two-phonon
