Layman's description

Nanotechnology is enabled by the diverse properties of materials at the nanoscale with, for example, particles consisting of several tens to hundreds of atoms or thin films of a few atomic layers finding applications in electronic devices and sensors.
The functionality of nanomaterials is critically dependant on atomic structure and local chemical bonding. To control and ultimately tailor this functionality, a fundamental understanding of the nature of atomic bonding is required. This project aims to build an integrated photoelectron spectroscopy suite (shared between Physics, Chemistry and Electronics) for the study of atomic bonding in sustainably-derived nanomaterials. A monochromatic X-ray source, for which funding is requested, is a crucial component necessary to complete the current spectroscopy lab in Physics.

Key findings

The objectives of this proposal were as following:
1.To enable the purchase of a monochromatic XPS source for the chemical analysis of functional nanomaterials.
2.To apply the source to the characterisation of novel nanomaterials grown by researchers in Physics, Chemistry, Electronics and Environment.
3.To provide maximum return on investment by contributing to securing future, large inter-departmental research grants.

Outcomes:
The newly established electron spectroscopy system has enabled a collaboration links between Physics and Chemistry department, and Physics and Electronics department. Currently the following research activities are undertaken in particular between the following groups:
1)Graphene functionalized starbone materials; between Advanced materials group ( Dr Lazarov and Dr Pratt) with Green chemistry ( Prof. Clark)
2)Photocatalyst materials; ( Dr Lazarov, Physics) and Dr Douthwaite (Chemistry)
3)Halfmetallic spintronics materials and band offset engineering ; Dr Lazarov, Dr Tear(Physics) and Prof. Hirohata ( Electronics)
