Enhanced sensitivity of partial O-terminated H-diamond for H2S detection at room temperature
N. Mohasin Sulthana, K. Ganesan, P. K. Ajikumar
The p-type surface conductivity of H-terminated diamond (HD) has opened new path ways to develop diamond based electronic devices, photo-catalysts, chemical and bio-sensors. Herein…
Raman and photoluminescence spectroscopic studies on structural disorder in oxygen deficient Gd2Ti2O7-d single crystals
M. Suganya, K. Ganesan, P. Vijayakumar +6
We report on Raman and photoluminescence spectroscopic studies on oxygen vacancy induced structural disorder in Gd2Ti2O7-d single crystals grown by optical floating zone technique…
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…
