Anomalous behavior of acoustic phonon mode and central peak in Pb(Zn1/3Nb2/3)0.85Ti0.15O3 single crystal studied using Brillouin scattering
K. K. Mishra, V. Sivasubramanian, A. K. Arora +1
Brillouin spectroscopic measurements have been carried out on relaxor ferroelectric Pb(Zn1/3Nb2/3)0.85Ti0.15O3 (PZN-PT) single crystal over the temperature range 300-585 K. The lon…
Phonon confinement and substitutional disorder in Cd1-xZnxS Nanocrystals
Satyaprakash Sahoo, S. Dhara, V. Sivasubramanian +2
1LO optical phonons in free-standing mixed Cd1-xZnxS nanocrystals, synthesized using chemical precipitation, are investigated using Raman spectroscopy. As expected for the nanocrys…

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…
Low Frequency Raman Scattering from Acoustic Phonon Confined in Nanoparticles in Borosilicate Glass
Sanjeev K. Gupta, Satyaprakash Sahoo, Prafulla K. Jha +2
Phonon modes found in low frequency Raman scattering from nanocrystals embedded in borosilicate glass arising from confined acoustic phonons are investigated. In ad…
Soft modes and NTE in Zn(CN)2 from Raman spectroscopy and first principles calculations
T. R. Ravindran, A. K. Arora, Sharat Chandra +2
We have studied Zn(CN)2 at high pressure using Raman spectroscopy, and report Gruneisen parameters of the soft phonons. The phonon frequencies and eigen vectors obtained from ab-in…
