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…
Spectroscopic Ellipsometry investigation on anisotropic optical properties of sputtered AlN films
Padmalochan Panda, R. Ramaseshan, S. Tripura Sundari +1
We report the uniaxial anisotropic optical constants of Wurtzite type AlN films deposited on Si (100) substrate using DC reactive magnetron sputtering as a function of growth tempe…
Reduction of residual stress in AlN thin Films synthesized by magnetron sputtering technique
Padmalochan Panda, R. Ramaseshan, N Ravi +5
We report the reduction in residual stress of AlN thin films and also the crystal structure, surface morphology and nanomechanical properties of magnetron sputtered as a function o…
Preferentially orientated E-beam TiN thin films using focused jet of nitrogen gas
R. Ramaseshan, Feby Jose, S. Rajagopalan +1
A modified electron beam evaporator has been used judiciously to synthesize TiN thin films with (111) preferred orientation. This new design involved in creating local plasma by ac…
Temperature dependence of dielectric constants in Titanium Nitride
S. Tripura Sundari, R. Ramaseshan, Feby Jose +2
The temperature dependence of optical constants of titanium nitride thin film is investigated using spectroscopic ellipsometry between 1.4 to 5 eV in the temperature range 300 K to…
Optical properties and hardness of highly a-axis oriented AlN films
Feby Jose, R. Ramaseshan, S. Tripura Sundari +4
This paper reports optical and nanomechanical properties of seldom studied highly a-axis oriented AlN thin films for the first time. These films were deposited by reactive DC magne…
