Electrical Transport in the Hybrid Structures of 2D Van Der Waals Materials and Perovskite Oxide
(2018-01-01)Perovskite oxides have provided a wide variety of exotic functionalities based on their unique physical and chemical properties. By combining different perovskite oxides, interesting physical phenomena have been observed ... -
Electrical transport study of Graphene/WSe2 Heterostructure
Spintronics has emerged as a novel platform to build information storage and logic devices in the last few decades. Graphene promises a long spin propagation length even at room temperature due to its low spin-orbit ... -
Electrical waves in mathematical models of human-ventricular tissue: effects of different modeling formalisms, electrophysiological factors, and heterogeneities on ventricular arrhythmias and the termination of these arrhythmias via a deep-learning approach
Sudden cardiac death (SCD) remains one of the significant causes of mortality in industrialized and developing countries. SCD is often caused by life-threatening cardiac arrhythmias like ventricular tachycardia and ... -
Electro-optic charge transport in semiconducting polymers
In this thesis, I have discussed the electric field dependence of photoconductivity of regioregular poly(3-hexylthiophene) [rr-P3HT] and its sensitization with Squaraine (SQ) dye. Even 1 wt % of SQ dye enhances the transport ... -
Electromagnetic waves in plasmas
This thesis embodies the investigations on the electromagnetic waves in plasmas. The investigations fall under two general headings, namely, wave propagation in plasmas in the presence of the Coriolis force (Part I) and ... -
An electromagnetically actuated mesoscale ball and socket joint for applications in 3-D metrology and electrical characterization
Micro-robotics is concerned with development of robotic systems to manipulate micro-meter sized objects. To develop functional micro-robotic manipulators, it is necessary to develop joints that possess large motion range ... -
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. ... -
Electron Paramagnetic Resonance and Magnetic Studies of Certain Doped Rare Earth Manganites
Doped rare-earth manganites with the general formula T1xDxMnO3 where `T' is a trivalent rare earth ion, e.g. La3+;Nd3+; Pr3+ etc. and `D' is a divalent alkaline earth ion, e.g Ca2+; Sr2+;Ba2+ etc. display various ... -
Electron Spin Resonance And Optical Studies On The Conducting Polymer Polyaniline
(2011-07-11)For every phenomenon found in inorganic materials, organic counterparts have been found in the last 50 years. The discovery of metallic conductivity in the inorganic conjugated polymer (SN)x was a forerunner to the discovery ... -
Electron spin resonance investigations of some fenoelectric sulphates
The present ESR work on Cu²? in (NH?)?SO? is reportedly the first one on the Cu²? ion doped as an impurity in a trigonal bipyramidal environment in a diamagnetic host lattice. The present study shows that the symmetry of ... -
