In response to a recently funded research project (ULTRA-LOWD) supported by the Independent Research Fund Denmark, we are pleased to announce a PhD position in the field of experimental ultrafast terahertz science and technology within DTU Fotonik at the Technical University of Denmark. The position is fully-funded for a period of three years.
Using a newly developed laser source that utilises hollow-core fibre technology and delivers intense, broadband THz radiation at unprecedented repetition rates (up to several MHz, with multi-kV/cm field strengths), this project will:
- Develop a complementary beam-line delivering wavelength tunable pulses covering the visible spectral region by harnessing nonlinear interactions in gas-filled fibre;
- Use these as-generated visible pulses in a transient absorption setup to both photo-excite and probe the ultrafast electronic response of low-dimensional crystalline materials subject to strong THz excitation;
- Explore the relationship between structural and electronic properties in two-dimensional (2D) semiconducting layered metal halide perovskites (MHPs).
This approach will allow us to unravel couplings between specific structural modes and relaxation pathways of hot charge-carriers, the role of excitons, and the formation and coupling of exciton complexes with the crystal lattice – all of which are not well understood in 2D MHPs. This fundamental understanding will have important implications for the development of future energy-efficient electronic devices to meet the challenges of a sustainable green society.
This is an open and unrestricted call. The successful candidate will be chosen based on their merits and suitability, but will be expected to have:
- An excellent record of academic performance from a recognised institution;
- A strong grounding in the foundations of nonlinear optics and solid-state physics;
- A proven interest in ultrafast spectroscopy;
- The ability to think laterally, propose solutions to complex problems and analyse experimental data within the framework of theoretical models;
- A good command of written and verbal English.
- A two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.
It would be a beneficial if the candidate has:
- Hands-on experience working in an ultrafast optics laboratory;
- Competency in Python, Julia, C++ etc for data analysis, modelling and visualisation.
We will offer you:
- A collaborative, engaging and stimulating working environment within which to rigorously pursue your scientific interests;
- Access to state-of-the-art laboratories equipped with leading-edge ultrafast laser infrastructure enabling a broad range of spectroscopic experiments;
- The opportunity to travel internationally to present your latest results at conferences and workshops, and perform research work at collaborating universities;
- A strong ethos of work-life-balance;
- A competitive salary.
Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.
