Tailoring excitonic complexes in layered materials
Layered transition metal dichalcogenides (TMDCs) host a variety of strongly bound
exciton complexes that control the optical properties in these materials. Apart from
spin and valley, layer index provides an additional ...
Medium Index Contrast Guided Mode Resonant Structures for Photonic Applications in the Visible-Near Infrared Wavelength Regime
Guided mode resonant (GMR) structures are interesting from the point of view of enhanced light-matter interaction and find applications in sensing, filtering, and miniaturized photonic components. The Guided mode resonance ...
Topics on Safety and Security of Power Systems
In this thesis, we investigate some of the problems concerning the safety and security of power systems. Since the operational safety of the power system itself is a vast area of research, we choose to investigate the ...
Investigations on Polygonal Voltage Space Vector Structure generation with lower order harmonic suppression using switched capacitive filter throughout modulation range for Drive Applications
Multilevel inverters (MLI) are widely used in a host of industrial applications ranging from renewable energy systems, to electric vehicles, to distributed generation. Due to the switching nature of the output voltage, MLI ...
Excitons in monolayer transition metal dichalcogenides
Excitons are quasiparticles formed due to electrostatic attraction between the electrons
and the holes in a semiconductor. This Coulomb attraction is very strong in the mono-
layers of Transition Metal Dichalcogenides ...
Algorithms for Fair Clustering
Many decisions today are taken by various machine learning algorithms, hence it is crucial to
accommodate fairness in such algorithms to remove/reduce any kind of bias in the decision.
We incorporate fairness in the ...
Addressing the Performance and Reliability Bottlenecks in 2D Transition Metal Dichalcogenide (TMD) Based Transistor Technology
In this thesis, we presented different contributions towards the development of
2D material technology. Firstly the realization of desired dimensions over singlecrystal
high-quality MoS2 material through dry etching ...
Modeling of Permittivity Variations in Stochastic Computational Electromagnetics
With the evolution of 5G systems offering high data rates, major changes are required in the design approach of the components of communication systems. Furthermore, building complex electromagnetic systems at the terahertz ...
Variational Bayes Algorithms for mmWave and Massive MIMO-OFDM Systems with Low Resolution ADCs
In this thesis, we develop novel low-complexity algorithms for massive multiple-input multiple-output (MIMO) systems under practical non-idealities and theoretically analyze their performance. The first problem we consider ...
Deep Learning Methods For Audio EEG Analysis
The perception of speech and audio is one of the defining features of humans. Much of the brain’s underlying processes as we listen to acoustic signals are unknown, and significant research efforts are needed to unravel ...
