Surface optical Raman modes in InN nanostructures
Satyaprakash Sahoo, M. S. Hu, C. W. Hsu +5
Raman spectroscopic investigations are carried out on one-dimensional nanostructures of InN,such as nanowires and nanobelts synthesized by chemical vapor deposition. In addition to…
Multi-phonon Raman scattering in GaN nanowires
S. Dhara, Sharat Chandra, G. Mangamma +9
UV Raman scattering studies show longitudinal optical (LO) mode up to 4th order in wurtzite GaN nanowire system. Frohlich interaction of electron with the long range electrostatic…
Blue luminescence of Au nanoclusters embedded in silica matrix
S. Dhara, Sharat Chandra, P. Magudapathy +8
Photoluminescence study using the 325 nm He-Cd excitation is reported for the Au nanoclusters embedded in SiO2 matrix. Au clusters are grown by ion beam mixing with 100 KeV Ar+ irr…
Blue shift of yellow luminescence band in self-ion-implanted n-GaN nanowire
S. Dhara, A. Datta, C. T. Wu +8
Optical photoluminescence studies are performed in self-ion (Ga+)-implanted nominally doped n-GaN nanowires. A 50-keV Ga+ focused ion beam (FIB) in the fluence range of 1x1014 -2x1…
