Postdoctoral Researcher in pyramidal site-controlled quantum dots grown in small (less than 2 microns) recesses

Contract: Full Time/ Specified Purpose

Tyndall National Institute at University College Cork invites applications for a Postdoctoral opportunity.

The Epitaxy and Physics of Nanostructures (EPN) group, Tyndall National Institution and University College Cork fund a Postdoc position on “on pyramidal site-controlled quantum dots grown in small (less than 2 microns) recesses “.

The Epitaxy and Physics of Nanostructures group is a well-established research team in Ireland addressing epitaxial growth of devices and quantum structures. E.g., quantum technology applications of III-V site-controlled quantum dots (see e.g. Gediminas Juska, et al. “Towards quantum dot based arrays of entangled photon emitters”, Nature Photonics 7, 527 (2013); T. H. Chung, et al. “Selective carrier injection into patterned arrays of pyramidal quantum dots for entangled photon light-emitting diodes”, Nature Photonics 10, 782 (2016)).
Moreover, EPN is part of both the Photonics and the Tyndall quantum centre: Quantum Computer Engineering Centre (QCEC).

The project is funded by an EU pathfinder award (QCEED), centred on quantum technology applications. The project is focused on the development of novel semiconductor cavities capable of enhancing photon extraction and photon quality for coupled site-controlled QDs, obtained in engineered small lithographic recesses. Pyramidal quantum dots are a very unique and specific system with its own challenges for developing cavity designs. For this reason we are seeking enthusiastic researchers with a strong background in single and coupled quantum dots, and specifically with strong experience on the epitaxy of site-controlled dots by MOVPE and their characterization.

Key Responsibilities

The main focus of this position is the development and the optical analysis/characterization of III-V and dielectric photonic cavities centred around single and coupled Pyramidal quantum dots.
The postdoc position will also involve collaborating with the rest of the EPN group on several other projects (aside of the Frontiers grant which also encompasses two other PhD positions), specifically on photonic chips, III-V material development and in general cryogenic optical characterization.
The successful candidate is also expected to engage broadly in PhD mentoring when possible.
Participate in Education and Public Engagement activities, as required.
Ensure all activities are compliant with the Tyndall Quality Management system.
Ensure all activities are compliant with the required Health and Safety standards.
Carry out any additional duties as may reasonably be required within the general scope and level of the post.

The Postdoc level position is open for candidates of EU and non EU nationalities. We welcome applications from talented candidates with strong motivation and experimental skills. The appointment is for two years. With the general possibility of further career development as specified by Tyndall career development opportunities.

Tyndall National institute has a proactive entrepreneurial culture and we welcome applications from candidates who possess entrepreneurial and creative skills/experience, including the creation of technology start-ups.

Essential Criteria

Postdoctoral applicants must hold a viva/PhD in Physics/Photonic Engineering or a related discipline before the start of the contract.
Experience in MOVPE of site-controlled quantum dots
They should have a rich CV and experience in quantum optics and photonics.

Desirable Criteria

Highly self-motivated applicants with strong experimental attitude.

Appointment may be made on the IUA Scale for Post-Doctoral Researchers €46,306- € 52,863 per annum. Salary placement on appointment will be in accordance with public sector pay policy.

Informal enquiries concerning these positions can be made to Dr. Emanuele Pelucchi.
Closing date of applications is 1pm, 14th November 2025.

Application Instructions
Please make sure to attach an up-to-date CV/Resume AND a brief motivation letter outlining how you meet the ‘Essential Criteria’ for this role.

Please note that Garda vetting and/or an international police clearance check may form part of the selection process.
