Towards an Integrated Graphene Nano-Opto-Electro-Mechanical System
Micro-electromechanical systems (MEMS) have found extensive applications in micromechanical
sensing. The scaling of MEMS into nano-electromechanical systems (NEMS) was spurred
primarily by the expectation of higher ...
Band-matched transport layers and intrinsically stable perovskite solar cells for application to perovskite Si tandem cells
Hybrid perovskite/silicon tandem solar cells offer low-cost alternatives to the commercially established silicon solar cells. In this thesis, we present the material and device optimizations of the subcells that can be ...
Resistive Switching and Electron Transport In Perovskite Oxide Thin Films
This work deals with the Resistive Switching (RS) properties of various perovskite oxides probed in a simple Metal - Insulator - Metal (M-I-M) configuration. The metals comprise of platinum which served as the bottom ...
Towards Logic Circuit Applications Using Solution Processed CNTs
With Silicon transistor technology reaching its practical limits, e orts to replace Si with
new materials with better electronic transport properties have gained considerable at-
tention. Single-walled carbon nanotubes ...
Polyurethane based Self-healing Nanocomposites for Electromagnetic Interference Shielding Applications
An augmentation in the growth of modern electronics and telecommunication has led to an increase in electromagnetic interference (EMI) as its aftermath. Device malfunctioning, unwanted noise and radio leakage are the direct ...
Design and development of high speed optical modulator on silicon-on-insulator platform
Optical communication has transformed information technology and enabled the present-day data explosion. The new era of data centric society is primarily driven by the ability to communicate data at high-speed. Migration ...
Exploring One-dimensional Micromechanical Resonators with Residual Stresses for Potential Sensing Applications and Measurement of Mechanical Properties
Recently the domain of microelectromechanical systems (MEMS) has seen an unprecedented rise in use of varieties of new materials other than the conventional silicon and related materials originally borrowed from semiconductor ...
Structural, Magnetic and Electrical Studies of Multiferroic BiFeO3 and CuO Epitaxial Thin Films
The multiferroics are an important class of multifunctional material which simultaneously possess spontaneous ferroelectric polarization and magnetic ordering. If there exists a coupling between the ferroelectricity and ...
Parametric Manipulation in 2D Material based NEMS Resonators
In this this thesis, I have studied dynamics of the two-dimensional (2D) material
based NEMS resonators with resonant frequency ranging typically from
10 MHz to 100 MHz. The experiment involved fabrication of the ...
Microwave synthesis of superparamagnetic cobalt-ferrite thin films for RF CMOS applications
In the era of 5G technologies, the emphasis is on getting all the devices, active or passive to work in high frequencies. Higher efficiency chips can be obtained by combining both the active and passive devices on a single ...
