Studies on ultra-short pulsed laser shock peening of stainless-steel in different confinement media
Kishore Elango, Jan S. Hoppius, Lalit M. Kukreja +2
Laser Shock Peening (LSP) of stainless-steel 316 and 316L was studied using Ti: Sapphire laser pulses of about 2 ps duration, maximum energy of about 1mJ and pulse repetition rate…
On femtosecond laser shock peening of stainless steel AISI 316
Jan S. Hoppius, Lalit M. Kukreja, Marina Knyazeva +4
In this paper we report on the competition in metal surface hardening between the femtosecond shock peening on the one hand, and formation of laser-induced periodic surface structu…
Resonance Raman mapping as an interface phonon probe in Si-SiO2 nanocomposites
Ekta Rani, Alka Ingale, A. Chaturvedi +2
Intermediate frequency range (511 - 514 cm-1) Si phonons in Si-SiO2 nanocomposites are shown to have contribution from both core1 and surface/interface1 Si phonons, where, ratio of…
Correlation of size and oxygen bonding at the interface of Si nanocrystal in Si-SiO2 nanocomposite: A Raman mapping study
Ekta Rani, Alka A. Ingale, A. Chaturvedi +6
Si-SiO2 multilayer nanocomposite (NCp) films, grown using pulsed laser deposition with varying Si deposition time are investigated using Raman spectroscopy/mapping for studying the…
Realization of epitaxial ZnO layers on GaP(111) substrates by pulsed laser deposition
S. D. Singh, R. S. Ajimsha, C. Mukherjee +3
Epitaxy of ZnO layers on cubic GaP (111) substrates has been demonstrated using pulsed laser deposition. Out of plane and in-plane epitaxial relationship of ZnO layer with respect…
Influence of morphological inhomogeneity induced carrier diffusion on transient photocurrent pulse shape in organic thin films
S. Raj Mohan, Manoranjan P. Singh, M. P. Joshi +1
The influence of film morphology induced carrier diffusion on the broadening of the time-of-flight transient photo-current pulse was investigated using Monte Carlo simulation in or…
