Phonon Confinement in Stressed Silicon Nanocluster
Satyaprakash Sahoo, S. Dhara, S. Mahadevan +1
Confined acoustic and optical phonons in Si nanoclusters embedded in sapphire, synthesized using ion-beam implantation are investigated using Raman spectroscopy. The l = 0 and l =…

Excitation energy dependence of electron-phonon interaction in ZnO nanoparticles
Satyaprakash Sahoo, V Sivasubramanian, S Dhara +1
Raman spectroscopic investigations are carried out on ZnO nanoparticles for various photon energies. Intensities of E1-LO and E2 modes exhibit large changes as the excitation energ…
