Students interested in these projects are encouraged to contact the group for more information. The group actively seeks applicants from all backgrounds.
PhD position “High-precision structural imaging of materials at the picometre scale” (September 2021 start)
The Ultramicroscopy Research Group, based at the Advanced Microscopy Laboratory – Trinity College Dublin, is offering one fully funded PhD position (4 years, stipend plus EU fees) for September 2021 start in the area of high-precision structural imaging of materials at the picometre scale.
The scanning transmission electron microscopy (STEM) facilities available at Trinity College Dublin are capable of imaging materials down to the atomic level. A high energy beam of electrons is concentrated to a spot less than 80 pm in diameter, scanned across a sample and atomic resolution images of scattering and spectroscopy signals can be collected. This makes STEM an indispensable technique for modern materials science and nanotechnology. However, the scanned nature of the acquisition, and the concentrated beam of electrons, presents difficulties in time resolution and specimen damage. The Ultramicroscopy Group is pushing developments in state-of-the-art beam-scanning strategies and hardware to mitigate this and advance the next generation of STEM.
This project will combine with the group’s recent developments and apply them to materials science problems in fields such as ferroelectricity. We are targeting the highest possible precision data with the least possible beam damage. We are keen to make use of our new, state-of-the-art segmented detector for differential phase contrast imaging. With this we want to push spatial and temporal resolution as well as quantitative measurements of electromagnetic fields. Quantitative assessment of data fidelity will be key and critical thinking skills will be essential.
This project will be supervised by Dr Jonathan Peters and Prof Lewys Jones. A stipend of €18,500 p.a. will be paid to the student (paid monthly). Fees are provided up to the EU fee level. Non-EU students will need to provide the fee difference.
Applicants should email a cover letter (1 page max.) and CV (2 pages max) to firstname.lastname@example.org. Applications will close at 5pm Friday 9th July. We hope to shortlist and interview very soon after.
The Ultramicroscopy Group and the School of Physics welcomes applications from all qualified candidates, and applications are particularly encouraged from all genders/ethnicities/backgrounds traditionally under-represented in Physics.
PhD position “Leveraging the modern data-science toolkit for atomic-resolution microscopy” (September 2022 start)
The Ultramicroscopy is offering one fully funded PhD position (4 years, stipend plus fees) for September 2021 start in the area of data-science in the scanning transmission electron microscopy (STEM). This project will see the student working closely with experimentalists to deliver new approaches in data-streaming, data-compression, feature extraction, and data visualisation. Research topics may include compressed-sensing, data in-painting and experiment design optimisation.
- The ideal applicant will have a 1st Class Honours Master's or Bachelor’s degree in Computer Science, Physics, Materials Science or related disciplines. Previous experience with electron microscopy is not necessary, but a background in programming or data-science is strongly preferred. The researcher will work closely with other members of a multidisciplinary project team. Excellent written and oral communication skills are essential.
- A stipend will be paid to the student (monthly). Fees are provided up to the EU fee level. Non-EU students will need to provide the fee difference.
Proposed Final-year Projects (September 2021 Start)
Final-year Physics undergraduate students interested in electron microscopy are encouraged to get in touch to discuss potential projects in the Advanced Microscopy Laboratory for 2020.
- "Using Low-cost Space-weather Sensors to Predict Atomic-scale Imaging Distortions"
- "Modelling Individual Impact Events in Electron Sensors"
- "Measuring Atomic Displacements with Sub-Picometre Precision"
- "Mapping the Crystallography of Solar-cell Materials at the Sub-micron Scale"
