Single Electron Tunneling at Large Conductance
In this dissertation I study electron tunneling in nanofabricated metallic structures. Specifically I consider systems containing metallic tunnel junctions that consist of two metallic electrodes separated by a thin oxide layer. Electrons in the leads are described by Fermi liquid theory and …

On the Dynamics of Single-Electron Tunneling in Semiconductor Quantum Dots under Microwave Radiation
… made in this thesis to reveal the dynamics of single-electron tunneling and to realize quantum bits (qubits) in semiconductor quantum dots. At low temperatures, confined single quantum dots and double quantum dots are realized in the twodimensional electron gas (2DEG) of AlGaAs/GaAs …

Design methodology for electron-trap memory cells
… further feature size reduction, the field of single-electronics has been developed. Single Electron Tunneling (SET) technology offers the ability to control the transport and position of a single or a small number of electrons. In this thesis we investigate the implementation of arithmetic …

h/e magnetic flux modulation of the energy gap in nanotube quantum dots
… carbon nanotubes act as the Coulomb island of a single electron tunneling transistor. Temperature dependence of the conductivity curves shows that the electron wave functions extend between electrodes, and the energy levels are well-defined so they can be traced. Differential conductivity maps of …

Digital to Analog Converter Design using Single Electron Transistors
… any will become a legitimate successor to CMOS. Single electron tunneling is a process by which electrons can be trans- ported (tunnel) across a thin insulating surface. A conducting island sepa rated by a pair of quantum tunnel junctions creates a Single Electron Transistor (SET). SETs exhibit …

A combined experimental and theoretical approach towards the understanding of transport in one-dimensional molecular nanostructures
… of the fascinating effects occurring in single wall carbon nanotubes (SWCNT). These particular nanostructures gained an overwhelming interest in the past two decades due to its outstanding electronic and mechanical features. We have investigated the properties of a novel family of carbon …

Functional nanoelectronic devices: single-electron transport, memristivity, and thermoelectricity in nanoscale flms using self-assembly and graphene
… on several experimental projects studying electronic transport in thin-flm electronic devices. Self-assembly methods and graphene were used to realise devices contacting films of self-assembled PbS quantum dots. The devices have exhibited single-electron tunnelling with a high yield. The …
