Raman Fingerprint of Pressure-Induced Phase Transitions in TiS3 Nanoribbons: Implications for Thermal Measurements under Extreme Stress Conditions
K. K. Mishra, T. R. Ravindran, Joshua O. Island +9
Two-dimensional layered trichalcogenide materials have recently attracted the attention of the scientific community because of its robust mechanical, thermal properties and applica…
Phonons and Anomalous Lattice Behaviour in KMnAg3(CN)6 and KNiAu3(CN)6: Inelastic Neutron Scattering and First-Principles Calculations
Baltej Singh, Mayanak K. Gupta, Ranjan Mittal +4
Cyanide based framework compounds are known to show large negative thermal expansion behaviour. Here we report the phonon and anomalous lattice behavior of two metal cyanide framew…
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…
Evolution and defect analysis of vertical graphene nanosheets
Subrata Ghosh, K. Ganesan, Shyamal R. Polaki +4
We report catalyst-free direct synthesis of vertical graphene nanosheets (VGNs) on SiO2/Si and quartz substrates using microwave electron cyclotron resonance - plasma enhanced chem…
Soft modes and NTE in Zn(CN)2 from Raman spectroscopy and first principles calculations
T. R. Ravindran, A. K. Arora, Sharat Chandra +2
We have studied Zn(CN)2 at high pressure using Raman spectroscopy, and report Gruneisen parameters of the soft phonons. The phonon frequencies and eigen vectors obtained from ab-in…
Acoustic vibrations of a silica-embedded gold nanoparticle: elastic anisotropy
Daniel B. Murray, S. Dhara, T. R. Ravindran +4
Spherical gold nanoclusters are grown by 1.8 MeV Au++ ion implantation into an amorphous silica matrix and subsequent air annealing at 873 K. Ultraviolet and visible light absorpti…
