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 ...
Investigations of Phase Change Memory Properties of Selenium Doped GeTe and Ge2Sb2Te5
(2018-04-05)
GeTe and Ge2Sb2Te5 alloys are potential candidates for non-volatile phase change
random access memories (PCRAM). For electrical data storage applications the materials should have stable amorphous and crystalline phases, ...
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 ...
A Study of Slow Modes in Keplerian Discs
(2018-02-25)
A rich variety of discs are found orbiting massive bodies in the universe. These could be accretion discs composed of gas around stellar mass compact objects fueling micro-quasar activity; protoplanetary discs, mainly ...
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 Multiscale Modeling Study of Iron Homeostasis in Mycrobacterium Tuberculosis
(2018-05-10)
Mycobacterium tuberculosis (M.tb), the causative agent of tuberculosis (TB), has remained the largest killer among infectious diseases for over a century. The increasing emergence of drug resistant varieties such as the ...
