\nDr Freya Johnson is a Visiting Researcher in the Department of Physics. Her research focuses on advanced materials for ultra-fast energy-efficient computing. Dr Johnson<\/span> has been using the facilities at Royce at Imperial including the Pulsed Laser Deposition, Atomic Force Microscopy, X-ray Diffraction, Cleanrooms and SPIN-lab to support her research. <\/span><\/strong>In this blog post, she discusses her research and her experience using the Royce facilities at Imperial.\u00a0<\/strong><\/p>\n

Can you tell us more about your research?<\/strong><\/p>\n

I am currently working on advanced materials for ultra-fast energy-efficient computing. Current computing technologies require a constant input of energy \u2013 which is mostly wasted as heat. I am developing nitride magnetic materials that can operate 1000x faster than current computers and have reduced losses, therefore saving energy.<\/p>\n

Why do you use the Royce facilities at Imperial for your work?<\/strong><\/p>\n

Royce at Imperial is the home of a state-of-the-art kit I couldn\u2019t really access anywhere else, so that was a big motivating factor. Also, getting access to the Royce facilities is straightforward, and nearly everything I need is located in the same area. So, I can grow a sample in the morning and be performing structural and surface analysis on the same sample in the afternoon, without any time wasted!<\/p>\n

Which facilities do you use at Royce?<\/strong><\/p>\n

Growth facilities (Pulsed Laser Deposition), Atomic Force Microscopy, X-ray Diffraction, Cleanrooms (Ion milling, E-beam lithography) and SPIN-lab \u2013 it is probably easier to list the facilities I don\u2019t use!<\/p>\n

In what ways did access to our facilities contribute to your research?<\/strong><\/p>\n

It is essential for my research. Using the facilities here has allowed me to develop new processes and new material combinations I have never tried before, with great success.<\/p>\n

Has working at the Royce facility led to any new insights or learning experiences?<\/strong><\/p>\n

Royce offers a space to interact with other users and find out about their projects. From this, I have had many new opportunities to collaborate and learn new things, which is a massive benefit to me!<\/p>\n

Royce at Imperial is a hub for start-ups, industry and academia to make, test and characterise materials, components and systems.<\/strong><\/em><\/p>\n
