Overview of the research

Graphene and the wider family of 2D materials are an exciting platform upon which to build the next-generation of electronic devices. From flexible transparent circuits, to new forms of switching devices, the unique properties of these nanoengineered layered systems have much potential for the realisation of new types of electron gun systems.

This primarily experimental project will focus on the production of new types of 2D layer electron tunnelling systems. Used in Xray sources, electron microscopy, travelling wave tubes, and microwave amplifiers, electron guns are a ubiquitous technology with significant societal and commercial worth.

Systematic 2D material growth studies will be conducted in the Group’s chemical vapour deposition reactors with the applicant expected to develop commercially viable and scalable transfer methodologies of the as-grown materials. The fabricated samples will be assessed using Bath University’s extensive metrology facilities, with the successful candidate’s research focussing on exploring the electron emission properties of these structures in the Group’s custom built ultra-high vacuum electron emission system.

The successful candidate should have a strong interest in nanomaterials and electron transport with a preference for experimental work. A hands-on approach and willingness to build and develop new systems and approaches to the outlined problem is extremely advantageous. A background in nanomaterial growth or advanced metrology is desirable.
