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…
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…
Monte Carlo Simulation of Carrier Diffusion in Organic Thin Films with Morphological Inhomogeneity
S. Raj Mohan, Manoranjan P. Singh, M. P. Joshi +1
Monte Carlo simulation was carried out to understand the influence of morphological inhomogeneity on carrier diffusion in organic thin films. The morphological inhomogeneity was co…
Negative electric field dependence of mobility in TPD doped Polystyrene
S. Raj Mohan, M. P. Joshi, Manoranjan P. Singh
A total negative field dependence of hole mobility down to low temperature was observed in N,N'-diphenyl-N,N'-bis(3-methylphenyl)-(1,1'-biphenyl)-4,4'diamine (TPD) doped in Polysty…
