This project will develop next-generation focused ion beam microscopy and nanofabrication using a novel cold ion source based on photoionisation of a laser-cooled atom beam. The low temperature and complex internal state structure of the constituent atoms combine to allow generation of ions with unprecedented brightness and resolution. We will use three unique and innovative ideas: field ionisation of atoms in so-called 'exceptional' states to reduce chromatic aberration; electron-ion correlations to enhance control of the ions at the nanoscale; and atom-atom interactions to isolate and manipulate individual ions. The new technology will enable advances in semiconductor nanofabrication and material characterisation.Read moreRead less

This project aims to support the practical applications of layered nanostructure-based devices and systems. The development of layered chalcogenide nanostructures is a global research focus due to their potential applications in the energy sector. However, their structure–property link is unclear due to the lack of direct correlation between their structure and properties. This project aims to establish the intrinsic structure–property link by closely correlating the structure (and structural variations) and properties (and varied properties) simultaneously determined from individual nanostructures inside a transmission electron microscope. Expected project outcomes may advance the knowledge base, and provide guidelines for the development of nanostructure-based devices for their high-performance applications, especially in the energy sector.Read moreRead less

Three dimensional nano-lithography: combined electron and ion beam fabrication. By adding one more dimension to a planar (hence two dimensional - 2D) lithography, it will become possible to structure and texture materials in three dimensions (3D) by combining electron beam lithography (2D) and ion beam milling (3D) with the highest precision of several nanometres. This will open new applications in photonics and sensing.
