Low temperature Raman study of Ca3Co2O6
Vinod panchal, Smita Gohil, Shankar Ghosh
We present low temperature Raman measurements on Ca3Co2O6. Shell model lattice dynamics calculations were done to determine the vibrational pattern of the expected Raman modes. In…
Non-monotonic size dependence of the elastic modulus of nanocrystalline ZnO embedded in a nanocrystalline silver matrix
Vinod Panchal, Shankar Ghosh, Smita Gohil +2
We present the first high pressure Raman study on nanocrystalline ZnO films with different average crystallite sizes. The problem of low Raman signals from nano sized particles was…
Raman and x-ray diffraction investigations on BaMoO4 under high pressures
Vinod Panchal, Nandini Garg, Surinder M. Sharma
X-ray diffraction and Raman scattering studies on scheelite structured barium molybdate show that, at 5.8 GPa, it undergoes a first order phase transition to fergusonite structure…
High Pressure phase transitions in BaWO4
Vinod Panchal, Nandini Garg, A. K. Chauhan +2
Using in-situ angle dispersive x-ray diffraction, we have shown that barium tungstate, which exists in scheelite phase at ambient conditions, transforms to a new phase about seven…
