Faraday rotation angle of the grown by Cd 0. It was inferred that CMT exhibit larger Phd course effect times larger than Terbium Gallium Garnet TGG currently used for optical isolators making it as an efficient material for optical isolator at longer wavelengths.
The thermoelectric properties of the sandwich structure formed between the II-VI and III-VI layered structure were studied and the efforts were carried out in understanding the underlying mechanism for better thermoelectric materials with the layered structure. The effect of different crystal growth planes and crystal shapes of BaMgF4 for subjected to poling at room temperature and higher temperatures to study the piezoelectric properties.
Owing to the fast growth rate, the segregation co-efficient tends to unity in EFG method; hence we are employing this method in growing other technologically important crystals as well. The studies of piezoelectric properties with variation of dopant concentration have been analyzed.
Materials results july 2013 as Sesquioxides, Alumina, Sapphire, Spinel, Zirconia, TiO2 optical composites and mid IR Chalcogenide optoceramics have been fabricated by spark plasma sintering SPS and the results obtained were compared with their respective single crystals. Freeze Isostatic Pressing Patent 6 Development of fluoride based transparent ceramics with the transparency from visible to far infrared for laser cutting machines Patent Anna university phd Study of thermodynamic evaluation of higher results july 2013 silicon and Cr-Si alloys to optimize the course work for thermoelectric applications were carried out.
D research work During the doctoral research program, several organic, inorganic and semi-organic nonlinear optical crystals were studied. The crystals were grown by low temperature solution growth technique, Bridgman technique and Czochralski techniques.
Some of the technologically important crystals like Sulphanilic acid, Glycine complexes and Bismuth silicate crystals were investigated. The thermodynamical parameters like interfacial energy, critical radius and critical nuclei were studied enabling the successful growth of defect free bulk crystals for device applications.
The optical vibrational frequencies, theoretically and experimentally were analyzed with density functional theory. In order to study the effect of the metal ions in the crystal lattice, by marriage proposal help precise control of ion concentration, swift heavy ion irradiation and ion implantation have been carried out.
The effects of various ions on anna university phd course work results july 2013 structural, optical, chemical and electrical properties of the crystal were analyzed continue reading.
The dosimetric properties of sulphanilic acid has been studied with the gamma ray irradiation and the initial results shows that the sulphanilic acid and its new complex sodium sulphanilate dihydrate exihibit anna university phd course work results july 2013 properties superior to the commercially available organic dosimeters.
Further glycine complexes such as glycine monophosphate, glycinium oxalate and glycine lithium sulphate have been investigated and their nonlinear and ferroelectric properties have been reported.
In addition the role of rare earth elements in the bismuth silicate crystals have been studied in detail. The piezoelectric response of the crystals anna university phd course work results july 2013 electrical poling has been dealt in details. The aforesaid anna university phd course work results july 2013 have been published in various international journals. Work experience in various labs during PhD: Helene de Lac, France 4.
