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 ... -
Issues in Phenomenology of Heavy Quarks And Leptons
(2017-09-26)The Standard Model (SM) of the particle physics, based on the gauge group SU(3) ×SU(2)L × U(1)Y , has been a successful theory which provides consistent description of all phenomena ranging from the nuclear beta decay to ... -
Iterative and direct P;Adic algorithms for exact solution of numerical problems
In this chapter, we have described an O(n³), 2 < P < 3 algorithm for inverting integer matrices using p-adic computations. Some of the important aspects of this method are: (a) Absence of any convergence problems – the ... -
Joint Eigenfunctions On The Heisenberg Group And Support Theorems On Rn
(2014-04-07)This work is concerned with two different problems in harmonic analysis, one on the Heisenberg group and other on Rn, as described in the following two paragraphs respectively. Let Hn be the (2n + 1)-dimensional Heisenberg ... -
Kinematical conservation laws and applications
Study of wave motion is important in the field of fluid mechanics. The equations governing the motion of an inviscid compressible fluid form a hyperbolic system of quasi-linear equations and hence give rise to nonlinear ...
