RD-8 PhD in thin-film transition metal dichalcogenide (TMD) devices for rigid and flexible substrates

Contract: Full Time/Fixed Term

Tyndall National Institute is a leading European research centre in integrated ICT (Information and Communications Technology) hardware and systems, specialising in both electronics and photonics – materials, devices, circuits and systems. In this project, we aim to carry out basic and applied research aligned in the area of novel functional materials applicable to active components in sensors, nano- and opto-electronics. More specifically, we are targeting to substantially increase the scalability, functionality, performance, and energy efficiency of electronic devices while keeping full compatibility with existing mass production technologies. The technical challenge involves the material modification of layered 2D semiconductors by advanced pulsed laser thermal treatment with timescales in the order of femto- to nano- seconds. This research aligns with Tyndall's ‘CMOS++' mission of developing ‘Deep Tech Innovation' for next generation ICT.

Transition metal dichalcogenides (TMDs) are a branch of 2D semiconductor materials that have high surface to volume ratios. TMDs impart very useful properties that can be exploited by the electronic device industry, ranging from switching devices in display technology, to high sensitivity gas sensors, and MOSFETs. Nanosecond pulsed laser annealing (PLA) has demonstrated benefits in its limited heat diffusion at nanosecond time scales, the thermal treatment is confined to the top 10-100 nm of the surface. The goal of this project is to enable the material modification of TMD semiconductors by femtosecond PLA processes ranging from infra-red to UV wavelengths. The project outputs aim to alleviate integrated circuit technology issues, and to enable new applications for thin-film TMDs on large area rigid and flexible substrates. Combining the skills of co-research teams in Tyndall and University of Galway, along with Academic Collaborators in the US and UK, our research team strives to implement collaborative research to unlock the unique synergy stemming from the complementarity of our expertise.

We now wish to hire a PhD student in thin-film transition metal dichalcogenide (TMD) devices for rigid and flexible substrates.

Essential Criteria

  • The minimum academic qualification is a 1st or upper 2nd class honours degree (or an equivalent international degree) in physics, electronic engineering, or related discipline.
  • Knowledge in semiconductor physics.
  • High degree of responsibility and independence. Self-motivation, initiative, and being achievement-oriented. Hands on and flexible attitude.
  • Excellent communication and interpersonal skills. Good presentation abilities, excellent written and oral English level.
  • Capability of working effectively within a team to achieve results. Able to collaborate with team members and project partners outside Tyndall.
  • Key challenges

  • To fabricate thin-film TMD electron devices on rigid and flexible substrates.
  • To extract figure-of-merits for thin-film TMD electrical parameters.
  • Literature review the subject area to benchmark new data against existing knowledge.
  • Tasks will incorporate electrical testing of the fabricated devices, and development of a methodology for metrology of TMD thin-film devices treated with PLA on rigid and flexible substrates. These studies will provide an excellent base for a career both in academia and in the high- value industry.
  • An annual student stipend of €18,500 applies for this successful candidate for this position. Yearly University academic fees will paid by the Tyndall National Institute.
