Summary on Grant Application Form |
|
The main aim of the proposal is to develop electrically-connected SWNT-AFM probes for high resolution electrical and electrochemical applications. Given the small diameter of SWNTs (~ 1 nm), high aspect ratio, well-defined geometry and high mechanical strength, SWNTs probes should offer significant advantages over conventional electrical and electrochemical scanned probe tips, such as increased spatial resolution (by at least an order of magnitude), eradication of tip wear, lower contact imaging forces and a defined tip geometry. Initial applications will include problems of great interest in materials science, such as imaging differing regions of dopant density in semiconductors and correlating surface structure with electrical conductivity in metal oxide thin films. The use of SWNT-AFM probes as nanoscopic electrodes will also be explored. Running concurrently with this work, an apparatus will be developed to enable the growth of aligned SWNTs and the possible discrimination between metallic and semiconducting tubes. Aligned tubes will significantly aid the development of conducting SWNT-AFM probes and are an important step towards the large scale fabrication of practical SWNT molecular scale devices.
