Research Fellow in On-Chip Optoelectronic Devices from 2D Materials (Nanophotonics), National University of Singapore

Job Description

This postdoc in nanophotonics at the National University of Singapore is a Research Fellow post developing on-chip multifunctional optoelectronic devices based on two-dimensional materials, in the College of Design and Engineering.

At a glance

• Position: Research Fellow
• Where: College of Design and Engineering, NUS Kent Ridge Campus, Singapore
• Pay: Not stated in the posting
• Duration: Not stated in the posting
• Apply: No closing date is given on the NUS careers portal, so the post is open until filled. ResearchJobs.in will re-check this listing on 21 October 2026.

The work spans the whole chain from growing the material to measuring a finished device: synthesis of high-quality 2D materials, fabrication of the optoelectronic devices, and characterisation and testing.

What the nanophotonics research fellow will do

• Controllably synthesise high-quality 2D materials — including 2D perovskites, chiral perovskites and 2D transition metal chalcogenides — by methods such as vapour deposition and solution growth, and characterise their photoelectric properties
• Use structural characterisation and photoelectric measurement to test lattice quality and performance, and feed the results back into the growth process
• Build efficient, ultra-compact on-chip optoelectronic devices using nanofabrication and van der Waals transfer
• Evaluate device performance parameters such as light emission efficiency, photoelectric conversion coefficient and carrier mobility, and optimise the fabrication process and test methods
• Couple metamaterials and photonic cavities to the devices to explore multifunctional applications such as spin sources, spin detectors and electrically pumped lasers

Why this role matters

Two-dimensional materials have been promising on-chip light sources for more than a decade, and the gap between a good flake and a working device has stayed stubbornly wide. It closes only when the same person controls the growth and the device, because the fabrication tells you what to change in the synthesis. This post is set up that way deliberately, and it adds the harder question on top: coupling to metamaterials and cavities to get chirality and electrically pumped emission rather than photoluminescence from a flake.

What NUS is looking for

• A PhD in materials science and engineering, photonics, optical engineering or a related field, with a solid background in nanophotonics, two-dimensional materials and optoelectronic devices
• Working experience and knowledge of nanophotonics, 2D materials, nanofabrication and optoelectronic device applications
• Experience in controllably synthesising a variety of high-quality 2D semiconductor materials
• In-depth theoretical and experimental expertise across material preparation, nanophotonics, device fabrication and application; practical experience in material synthesis, device fabrication and characterisation is preferred

Pay and location

The posting does not state a salary or a contract length. The role is at the Kent Ridge Campus in Singapore, within the College of Design and Engineering.
