Title Proper : Engineering the electromagnetic environment in a nanostructure to study single electron tunneling
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : In this research the electromagnetic environment in a ballistic semiconductornanostructure is engineered to study single electron tunneling oscillations: the repet-itive tunneling of individual electrons through an energy barrier causing a saw-toothvariation in the voltage across the barrier. In this work, novel use of staggered arraysof quantum point contacts as ballistic resistors in a two-dimensional electron gas pro-vides a high impedance environment for a tunnel barrier placed between the arrays.Since instantaneous establishment of charge equilibrium with the potential source isprevented, strong Coulomb charging is observed for the barrier. This approach cir-cumvents problems faced by metallic thin-film resistors, for which stray capacitive....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
