Spatially resolved Raman spectroscopy study of uniform and tapered InAs micro-nano wires: Correlation of strain and polytypism
Vandna Kumari Gupta, Alka A. Ingale, Suparna Pal +2
The asymmetric peak at 212 - 218 cm-1 occurring in InAs micro-nano wires is investigated using spatially resolved Raman spectroscopy (SRRS) of uniform, bent and long tapered MNWs g…
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…
One step growth of PVP spheres embedded with nearly monodispersive CdS nanocrystals using chemical bath deposition
Alka A Ingale, Rahul Aggarwal, Ekta Rani +3
We have used simple chemical bath deposition technique to grow nearly monodispersive CdS nanocrystals in PVP matrix. Systematic study of variation of growth parameters has revealed…
Ultrafast optical generation of coherent phonons in CdTe1-xSex quantum dots
A. V. Bragas, C. Aku-Leh, S. Costantino +3
We report on the impulsive generation of coherent optical phonons in CdTe0.68Se0.32 nanocrystallites embedded in a glass matrix. Pump probe experiments using femtosecond laser puls…
Swift Heavy Ion Induced Modification Studies of C60 Thin Films
Navdeep Bajwa, Alka Ingale, D. K. Avasthi +3
Modification induced by 110 MeV Ni ion irradiated thin film samples of C60 on Si and quartz substrates were studied at various fluences. The pristine and irradiated samples were in…
