Structural, optical and mechanical properties of Y2Ti2O7 single crystal
M. Suganya, K. Ganesan, P. Vijayakumar +3
We report on the growth of Y2Ti2O7 single crystals by optical floating zone technique. X-ray diffraction and Raman spectroscopy studies confirm the structural quality of the crysta…
Structural, Raman and photoluminescence studies on nanocrystalline diamond films: Effects of ammonia in feedstock
K. Ganesan, P. K. Ajikumar, S. K. Srivatava +1
Herein, we report on the improvement of structural quality and enhancement of photoluminescence (PL) emission for an optimally N doped nanocrystalline diamond (NCD) film. Pure and…
Role of microstructure and structural disorder on tribological properties of polycrystalline diamond films
P. K. Ajikumar, K. Ganesan, N. Kumar +3
Polycrystalline diamond films with systematic change in microstructure that varies from microcrystalline to nanocrystalline structure are synthesized on Si by hot filament chemical…
Si and N - vacancy color centers in discrete diamond nanoparticles: Raman and fluorescence spectroscopic studies
K. Ganesan, P. K. Ajikumar, S. Ilango +2
The present study reports on an innovative method to prepare discrete diamond nanoparticles or nanodiamonds (NDs) with high structural and optical quality through top-down approach…
