Project summary:
Nanoscience is the study of phenomena and manipulation of materials at atomic, molecular and macromolecular scales, where properties differ significantly from those at a larger scale. In the past several years, many groups have used synchrotron radiation at the SRS to characterise the electronic and structural properties of diverse nanosystems; indeed the SRS has acted as a hub for UK nanoscience through these activities. However much of this activity has been hampered by the fact that many nanosystems can only be characterised by direct imaging, which has not been available at the SRS.
This proposal is to enhance the quality of nanoscience on the SRS through the incorporation of an ultra-high-vacuum scanning tunnelling microscope (STM) on a new general purpose end-station. The STM will facilitate preliminary characterisation of a wide range of nanoscale systems prior to measurements of their electronic and quantitative structural properties using synchrotron radiation techniques. This will give UK researchers in nanoscience an extra competitive edge internationally and will lay the groundwork for similaar developments at future UK synchrotron facilities.
Project objectives:
The objectives of the project are:
(a) design, commissioning and installation of a new vacuum vessel and pumping system optimised for the inclusion of a scanning tunnelling microscope including elimination of any vibrational and electrical noise problems;
(b) carrying out of three experiments in ’Äúflagship’Äù areas:
(i) Electronic
properties of aperiodic nanosystems
(ii) Superlattices and
supermolecular assemblies
(iii) Device and cluster
nanoscience
Personnel:
The development will be implemented by Dr. Vin Dhanak and George Miller.
