Pulsed Laser Ablated Dilute Magnetic Semiconductors and Metalic Spin Valves
(2018-04-02)
Spintronics (spin based electronics) is a relatively new topic of research which is important both from the fundamental and technological point of view. In conventional electronics charge of the electron is manipulated and ...
Modelling, Fabrication and Characterization of HgCdTe Infrared Detectors for High Operating Temperatures
(2018-02-23)
In this work, we have designed, simulated, fabricated and characterized homojunction Hg1-xCdxTe detector for high operating temperature in the MWIR region. The IR photon detectors need cryogenic cooling to suppress thermal ...
Role of Excess Fe in Pristine and Substituted Fe Chalcogenide Superconductors
(2018-03-02)
Fe chalcogenides : The discovery of superconductivity in Fe based compounds trig-
gered an intense research activity in this field with significant importance given to
material synthesis. As a result, numerous materials ...
Development of a Spin-Polarized Low Energy Electron Diffraction System and Investigation on Spin-Orbit and Exchange Interactions on Ir(100) and Ultrathin Fe(100) Grown on Ir(100)
(2018-02-28)
Spin-polarized electron beam has not yet been produced from an unpolarized electron beam using Stern-Gerlach type spin filter, because of the Lorentz force and Heisenberg uncertainty principle. At present, electron spin ...
The Many Facets of Variabilities in X-ray Binaries
(2018-02-28)
More than half a decade of X-ray astronomy with various balloon borne and space orbiting X-ray instruments, have led to discoveries and detailed studies of X-ray binaries. An important property of X-ray binaries is intensity ...
Growth and Physical Properties of Biaxial Nonlinear Optical Crystals of Ascorbic Acid Family
(2018-02-26)
Saccharides, a class of organic materials, are potential candidates for nonlinear optical applications. Ascorbic acid is a sugar acid and is classified as a monosaccharide. The molecule of ascorbic acid has two chiral centers ...
Electron Filed Emission Studies of Nanostructured Carbon Materials
(2018-03-08)
Field emission is the emission of electrons from a solid under an intense electric field, of the order of 109 V/m. Emission occurs by the quantum mechanical tunneling of electrons through a potential barrier to vacuum. ...
A Study of Superbubbles in the ISM : Break-Out, Escape of LYC Photons and Molecule Formation
(2018-02-16)
Multiple coherent supernova explosions (SNe) in an OB association can produce a strong shock that moves through the interstellar medium (ISM). These shocks fronts carve out hot and tenuous regions in the ISM known as ...
Impact of Disorder and Topology in Two Dimensional Systems at Low Carrier Densities
(2018-02-15)
Two dimensional (2D) systems with low carrier density is an outstanding platform for studying a wide spectrum of physics. These include both classical and quantum effects, arising from disorder, Coulomb interactions and ...
Engineering Plasmonic Interactions in Three Dimensional Nanostructured Systems
(2018-02-08)
Strong light matter interactions in metallic nanoparticles (NPs), especially those made of noble metals such as Gold and Silver is at the heart of much ongoing research in nanoplasmonics. Individual NPs can support collective ...
