Mesoscopic Conductance Fluctuations in Disordered Graphene
This thesis is focused on an experimental study of the fluctuations in the conductance of disordered graphene flakes. Conductance fluctuations (CF) are generated by varying either magnetic field (±8 T) or Fermi energy (via ...
Electronic structure imperfections and chemical bonding at graphene interfaces
The manifestation of novel phenomena upon scaling to finite size has inspired a paradigm shift in materials science that takes advantage of the distinctive electrical and physical properties of nanomaterials. Remarkably, ...
Toward Nanoscale Material Applications: Colloidal Quantum Dot Memory And Multi-Layer Graphene Electronics And Optoelectronics
In this dissertation, the analysis of a possible use of colloidal semiconductor quantum dots (QDs) in memory storage devices is presented. The charging and discharging behaviors of capped cadmium selenide (CdSe) QDs deposited ...
Towards lightweight nanocomposite coatings for corrosion inhibition: Graphene, carbon nanotubes, and nanostructured magnesium as case studies
The field of nanocomposites is a burgeoning area of research due to the interest in the remarkable properties which can be achieved through their use in a variety of applications, including corrosion resistant coatings. ...
Probing cyclotron resonant signatures and the AC quantum Hall effect in monolayer and heterogeneous graphene multilayers through mid-infrared, magneto-optical, polarization-sensitive spectroscopy
In 1947 Phillip Wallace introduced the fundamental electronic properties of a single layer of graphite, known as graphene. At that time, graphene was introduced as a theoretical tool that could be used to approximate the ...
Fast Energy Relaxation of Hot Carriers Near the Dirac Point of Graphene
We investigate energy relaxation of hot Dirac fermions in monolayer and bilayer graphene devices. Conductance fluctuation thermometry is used to determine the effective carrier temperature at any current, and to compute ...
