Structural, optical and mechanical properties of Cr doped \b{eta}-Ga2O3 single crystals
P. Vijayakumar, K. Ganesan, R. M. Sarguna +6
Undoped and Cr doped \b{eta}-Ga2O3 (100) single crystals are grown by optical floating zone method. The full width at half maximum of rocking curve is found to be 106 arcsec for un…
Growth and inelastic light scattering studies on Sr2Nb2O7 single crystals
M. Suganya, P. Vijayakumar, V. Sivasubramanian +4
A crack free and high structural quality Sr2Nb2O7 single crystals were grown by the optical float zone method using optimized growth parameters. Laue pattern confirms single crysta…
Growth of large-sized relaxor ferroelectric PZN-PT single crystals by modified flux growth method
P. Vijayakumar, C. Manikandan, R. M. Sarguna +5
A novel bottom-cooling high-temperature solution growth technique is developed for growing large-sized relaxor ferroelectric 0.91Pb(Zn1/3Nb2/3O3)-0.09PbTiO3 (PZN-PT) single crystal…
Development of travelling heater method for growth of detector grade CdZnTe single crystals
P. Vijayakumar, Edward Prabu Amaladass K. Ganesan R. M. Sarguna, Varsha Roy +1
We report on the indigenous design and development of laboratory scale travelling heater method (THM) system to grow detector grade Cd0.9Zn0.1Te (CdZnTe) single crystals. THM syste…
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, 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…
