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…
Exploring the substrate-driven morphological changes in Nd0.6Sr0.4MnO3 thin films
R S Mrinaleni, E P Amaladass, S Amirthapandian +9
Manganite thin films are promising candidates for studying the strongly correlated electron systems. Understanding the growth-and morphology-driven changes in the physical properti…

Structural and optical properties of beta irradiated YAlO3 single crystals
M. Suganya, K. Ganesan, P. Vijayakumar +6
We report on the growth, structural and optical properties of YAlO3 single crystals grown by optical floating zone technique. Powder X-ray diffraction and Raman spectroscopic studi…
Superconducting Fe(1+delta)Se(1-x)Te(x) thin films: Growth, characterization and properties
T. Geetha Kumary, Dipak Kumar Baisnab, J. Janaki +5
Thin films of Fe(1+delta)Se(1-x)Te(x) (delta ~ 0.18 & x ~ 0.5) have been successfully grown on (100) oriented single crystalline SrTiO3 and LaAlO3 substrates by pulsed laser deposi…
