EP-27 Researcher - MOVPE growth of III-V semiconductor material and nanostructures 

Contract: Full Time/Fixed Term

The Epitaxy and Physics of Nanostructures (EPN) group, Tyndall National Institution and University College Cork fund a Post-Doc position on “MOVPE growth of III-V semiconductor material and nanostructures “.

The Epitaxy and Physics of Nanostructures group is a well-established research team in Ireland addressing epitaxial growth by MOVPE of devices and quantum structures. We are seeking highly self-motivated applicants with strong experimental attitude to apply for this position.

Key Responsibilities

The research will focus on developing applications with semiconductor, largely based on novel nanostructure concepts and expanding the Tyndall unique metamorphic platform. The candidate will be called to contribute to the group effort towards the realisation of advanced planar devices, such as broadband emittters, temperature insensitive lasers, high speed modulators and others. Recent results on the unique system developed at Tyndall were featured in major reviews, such as Nature Photonics (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)). Similarly EPN has been at the forefront of growth understanding and modelling, see e.g.:  A. M. Gocalinska et al.,” Early stages of InP nanostructure formation on AlInAs”, Phys Rev. B 101, 165310 (2020) and E. E. Mura, et al., “Importance of Overcoming MOVPE Surface Evolution Instabilities for >1.3 μm Metamorphic Lasers on GaAs”, Cryst. Growth Des. 2021, 21, 4, 2068–2075

The main focus of this position is developing novel epitaxial growth protocols to develop advanced site-controlled quantum dot structures, capable of hosting excitonic Wigner molecule assemblies. The work will include running structural characterization techniques, such as AFM and XRD, as guidance in the development of such structures.

The postdoc position will also involve collaborating intensively with the rest of the EPN group and collaborating ones (e.g. B. Corbett and F. Peters), including growth and structural characterization of more conventional device structure (lasers, modulators, LEDs, etc.), or any other projects such as polycrystalline III-V on foreign substrates.

The successful candidate is also expected to collaborate with the rest of the EPN group on industrial engagement and projects.

The successful candidate is also expected to engage in PhD mentoring and supervision, and also follow Tyndall outreach engagement policies.

Other responsibilities

• 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.

Essential criteria

• Postdoctoral applicants must hold a PhD in Physics or a related discipline before the start of the contract.
• Applicants have a rich CV and experience in some of the following: MOVPE or other epitaxy (e.g. MBE), quantum optics with quantum dots, cleanroom processing, transfer print, photonic simulations and photonic integration. Or at least in a field close to the topics to be investigated.
• First class university and research curriculum

Desirable Criteria

• Highly self-motivated applicants with strong experimental attitude.
• A high number of scientific publications
• Preference will be given to candidates with strong background in at least one of the following areas: MOVPE or MBE growth of nanostructures, QDs as light sources, cleanroom processing, transfer print, photonic circuit simulations and photonic integration.

The Epitaxy and Physics of Nanostructures group was established in January 2007 at Tyndall National Institute (http://www.tyndall.ie) under an SFI (http://www.sfi.ie/home/index.asp) Principal Investigator grant. The group is led by Dr. E. Pelucchi.

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 one year with the possibility of extension (up to three years), and previous experience in the field is preferentially requested.

Appointment may be made on the IUA Researcher Scale €38,630-€45,942 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 (emanuele.pelucchi@tyndall.ie).
