Tuning light matter interaction in magnetic nanofluid based field induced photonic crystal-glass structure by controlling optical path length
Junaid M. Laskar, Baldev Raj, John Philip
The ability to control the light matter interaction and simultaneous tuning of both structural order and disorder in materials, although are important in photonics, but still remai…
A complete Raman mapping of phase transitions in Si under indentation
C. R. Das, H. C. Hsu, S. Dhara +7
Crystalline Si substrates are studied for pressure induced phase transformation under indentation at room temperature using Berkovich tip. Raman scattering study is used for the id…
Mechanism of recrystallization process in epitaxial GaN under dynamic stress field - Atomistic origin of planar defect formation
C. R. Das, S. Dhara, H. C. Hsu +6
The mechanism of recrystallization in epitaxial (1000) GaN film, introduced by indentation technique, is probed by lattice dynamic studies using Raman spectroscopy. The recrystalli…
Recrystallization of epitaxial GaN under indentation
S. Dhara, C. R. Das, H. C. Hsu +6
We report recrystallization of epitaxial (epi-) GaN(0001) film under indentation.Hardness value is measured close to 10 GPa, using a Berkovich indenter. Pop-in burst in the loading…
Deformation potential dominated phonons in ZnS quantum dots
S. Dhara, A. K. Arora, Jay Ghatak +5
Strong deformation potential (DP) dominated Raman spectra are reported for quantum confined cubic ZnS nanoclusters under off-resonance conditions allowed only in quantum dots. A fl…
Microstructural studies on lattice imperfections in irradiated Titanium and Ti-5%Ta-2%Nb by X-Ray Diffraction Line Profile Analysis
P. Mukherjee, A. Sarkar, P. Barat +2
The microstructural parameters like the average domain size, effective domain size at a particular crystallographic direction and microstrain within the domains of titanium and Ti-…
