Investigations on Photophysical Properties of Semiconductor Quantum Dots (CdxHg1-xTe,Ag2S) and their Interactions with Graphene Oxide, Organic Polymer Composites
(2018-02-07)The motivation of this thesis is to understand the physical properties of semiconductor quantum dots (QDs) and to get insight on the basic physics of charge separation in composites made from QDs with graphene oxide ... -
Investigations on structural, optical and electrical properties of lattice matching CdZnTe & HgCdTe colloidal quantum dot systems for possible core-shell structures in optoelectronic devices
In this work, alloyed II-VI group CdZnTe, HgCdTe colloidal quantum dots (QDs) have been synthesised and their optical, material, electrical properties are studied for optoelectronic applications. The bandgap of the alloyed ... -
Investigations On The Influence Of Process Parameters On The Deposition Of Samarium Cobalt (SmCo) Permanent Magnetic Thin Films For Microsystems Applications
(2011-02-15)The research in permanent magnet thin films focuses on the search of new materials and methods to increase the prevalent data storage limit. In the recent past the work towards the application of these films to micro systems ... -
Investigations on the Mechanical threshold in IV-V-VI Glasses
The main features observed in the DSC studies of Ge–As–Te glasses are the following: (i) The T? versus ?r? plot for the two families of Ge–As–Te glasses shows a linear increase with ?r?, with a small change in slope at ?r? ... -
Investigations On Topological Thresholds In Metal Doped Ternary Telluride Glasses
(2009-06-16)The ability to tune the properties over a wide range of values by changing the additives, composition, etc., has made chalcogenide glassy semiconductors, most interesting from both fundamental physics as well as technology ... -
Ion Assisted Deposition Of HfO2 Thin Films For CMOS Gate Dielectric Applications
(2013-09-13)The scaling down of Complementary Metal Oxide Semiconductor (CMOS) transistors to sub-100nm requires replacement of conventional Silicon dioxide layer with high dielectric constant (K) material for gate dielectric. Among ... -
Iridates, Black Phosphorus, Weyl and Dirac Semimetals Under Extreme Conditions : Raman Study
This thesis presents Raman studies of Sodium iridates (Na2IrO3 and Na4Ir3O8), VO2, black phosphorus, Weyl (TaAs, TaP, NbP and NbAs) and Dirac (Cd3As2) semimetals under ex-treme conditions like low temperature (upto 4K), ... -
Irreducible Representations Of The Symmetric Group And The General Linear Group
(2013-01-31)Representation theory is the study of abstract algebraic structures by representing their elements as linear transformations or matrices. It provides a bridge between the abstract symbolic mathematics and its explicit ...
