Nanodevices of Graphene, Carbon Nanotubes and Flow Behaviour of Graphene Oxide Gel
(2018-05-09)
In the last three decades carbon nanomaterials such as fullerenes, carbon nanotubes and graphene have attracted significant attention from the scientific community due to their unique electronic, optical, thermal, mechanical ...
Optoelectronic Properties of Graphene Based Van-der-Waals Hybrids
Light matter interactions in atomically thin van der Waals materials have attracted significant attention in recent day [1–6]. Although the thickness does not exceed few nano-meters, such an atomically thin materials alone ...
Emergent Phenomena from Contacts and Disorder in High Mobility Graphene
The discovery of graphene and analogous van der Waals materials offers a platform for the discovery and exploration of various novel physical phenomena. Here we study the effects of local interaction and strong localisation ...
Study of Photo-generated Charge Transport in Graphene-based Hybrid Structures
Hybrid structures involving atomic/molecular membranes from two or more layered materials
are emerging as a platform for novel class of field effect transistors (FETs), p - n
junctions, photo-detectors, photo-voltaic ...
Tuning the electrical and thermoelectric properties of bilayer graphene by band engineering
Graphene and its two dimensional (2D) analogues have sustained the interests of the
researchers for quite some time because of the rich physics they offer including many
quantum phenomena and non-trivial topological ...
Development of Graphene Based Sensors for Human Physiological Monitoring and Vacuum Measurement
Nanomaterials have emerged as a remarkable class of materials in recent years owing to their excellent electrical, chemical, and physical properties. The first two-dimensional (2D) material to be discovered, graphene, has ...
Vertically aligned carbon nanostructures using ECR plasma and their applications
Vertically aligned carbon nanostructures are a type of carbon nanomaterial in which
nanostructures are aligned lengthwise perpendicular to the plane of the substrate. In this thesis
work, two vertically aligned carbon ...
Studies of Diamagnetism and Thermoelectric Transport in High Temperature Superconductors and Graphene
Using a recently proposed Ginzburg-Landau-like free energy functional due to Banerjee et al. Phys. Rev. B 83, 024510 (2011) we calculate the fluctuation diamagnetism of high-T c superconductors as a function of doping, ...
Study of Optoelectronic Properties of Quantum Emitter Assemblies Coupled to Graphene, Photonic and Plasmonic Materials
Nano-photonics deals with different ways to control light-matter interactions beyond the diffraction limit. In contrast to optics, which is the concept of light rays, including absorption, transmission, and reflection, ...
Ultrafast Photoexcited Carrier Dynamics in Low Dimensional Systems Probed by Time Resolved Terahertz Spectroscopy
The key aspect of this thesis is to understand the photoinduced carrier dynamics in low dimensional systems by employing time resolved optical pump-terahertz probe (OPTP) spectroscopy. Ultrafast pulsed laser (Ti: Sapphire ...
