PhD - Development of Interface Materials for Magnesium-Based Thermoelectric Devices
About Tyndall
Tyndall National Institute is an international leader in semiconductors, photonics and deep-tech research and innovation. As a leading collaborative European research institute, Tyndall is a key actor and hosting partner in the delivery of the ‘Chips for Europe Initiative’ (EU Chips Act).
Tyndall is Ireland’s leading research and innovation organisation and it is the national focal point for excellence in deep-tech research, development and graduate training at the convergence of nanotechnology, microelectronics, photonics, electronics and AI. Tyndall is recognised as an international research leader in semiconductor, chip and digital technologies, particularly as applied to the fields of Information & Communications, Health & Life Sciences, Agritech & Food Security, Energy and Climate Mitigation, emerging fields such as quantum, and novel computing paradigms.
The Institute’s key objective is to see frontier research activities having a significant impact on economic development and societal challenges in Ireland, Europe and beyond. Central to Tyndall’s mission is delivering economic impact through research excellence in partnership with industry and academia. With an annual turnover of more than €50m, the Institute has a community of over 600 researchers, engineers, support staff, postgraduate students, interns and industry researchers-in-residence.
With significant committed Irish government support, Tyndall will grow to be 1,000 people by 2030, with approximately 750 researchers, including 250 PhD students. A new 17,000 m2 research building is under development adjacent to the Cork headquarters and there are developing plans to expand Tyndall’s existing Dublin research labs and to establish other research sites within Ireland.
Tyndall’s expansion is also supported by recent national and EU funding wins for significant (M€10’s) additional research equipment across a range of areas such as semiconductor processing, microscopy, quantum technologies, heterogeneous integration, ultra-high speed optical communications and RF through THz characterisation.
About the MGICIAN Doctoral Network
MGICIAN is a Horizon Europe MSCA Doctoral Network dedicated to developing sustainable magnesium-based thermoelectric materials and translating them into high-performance solid-state cooling technologies. The network brings together academic and industrial partners across Europe and trains 15 Doctoral Candidates (PhD students) in materials development, interface engineering, module fabrication, and system integration.
About the Role
The PhD student will focus on the development and evaluation of advanced interface material schemes for magnesium-based thermoelectric devices used in solid-state cooling applications within the MGICIAN Doctoral Network. The project will address the design and optimisation of interface materials and bonding strategies to achieve low electrical contact resistance, mechanical robustness, and long-term stability. Particular emphasis will be placed on compatibility with magnesium-based thermoelectric systems and industrially relevant fabrication routes.
The project will combine electrical, thermal, structural, and thermo-mechanical characterisation to establish interface-performance relationships and identify processing- and operation-induced failure mechanisms, ensuring integration compatibility with thermoelectric modules developed within the consortium.
Key Duties & Responsibilities
The PhD student will:
