Formation and characterisation of electroanalytical junctions

Abstract

Electrochemical and microscopy techniques are used to form and investigate novel nanojunctions. Initial investigative work is carried out using junction arrays formed via layer-by-layer deposition techniques. In depth studies into novel paired gold junction electrodes formed using simple electrochemical deposition techniques are provided along with subsequent characterisation and application as electrochemical sensors.

The aims of the project are to create a novel method of junction electrode production, which consists of a simple single step deposition technique. These junctions should be easily produced with variable sizes between the electrodes reaching down to the nanometer scale.

The study will include information into effects of gap size within the junction electrodes as well as full characterisation and applications as electrochemical sensors. Finally, a novel multi-phase junction experiment will be demonstrated using paired triple phase boundary ion transfer.
