We are looking to hire an excellent and very motivated student to conduct a PhD project in X-ray metrology of materials. She/He/They will develop a novel approach to material metrology that combines attosecond (to few femtoseconds) transient measurements to 2D- 3D in situ- imaging enabled by X-ray Coherent Tomography (XCT). X-ray coherent tomography (XCT) originally is a static cross-sectional imaging of solids inspired from optical coherent tomography in the infrared. Unlike other X-ray imaging technique that requires monochromatic X-ray sources to overcome the chromaticity of the imaging optics (zone plates or multilayer optics), XCT uses broadband extreme ultraviolet radiation to achieve nanometric resolution for the metrology of target. Recently, XCT was demonstrated in the XUV range (30-100 eV) using high harmonic generation onto silicon based target to reveal the 3D imaging of the target sample [1]. We propose to resolve temporally and spatially the dynamical process involved in relevant bulk materials and metamaterials after excitation or ionization using pump-probe scheme [2]. The ‘Attosecond XCT’ project will be held at both the Attosecond Physics Laboratory at King’s College London situated at the heart of London, UK and on X-ray Free Electron laser infrastructure (XFEL).
Candidate Requirements:
The candidate should have completed an MSc in Physics with strong photonics components to high standard (overall marks equivalent to first -class honours degree or above 80%).
The candidate should have prime expertise in either:
· X-ray imaging
· Ultrafast pump-probe experiment
· Attosecond-femtosecond Physics or strong field- matter interaction
· Data analysis using matlab or python
· Excellent communication skills
· Excellent English written and spoken communication skills see https://www.kcl.ac.uk/study/postgraduate/apply/entry-requirements/english-language.aspx
· Team working
The candidate should have secondary expertise in either:
· Condensed matter physics
· Quantum materials
· Metamaterials
· Machine learning
Successful candidate will participate to the group activities and be supported to take initiative and participate to conferences and collaborations.
Start date: October 2022
