The LUMINOUS! Centre of Excellence for Semiconductor Lighting and Displays at NTU is seeking a Research Fellow (Single-Photon Emission Characterization & Ultrafast Optical Instrumentation) to support an NRF-funded project on electrically driven single-photon-emitting diodes based on colloidal quantum wells. The role involves setting up single-photon-emission characterization capabilities and performing advanced electrical, optical, and single-photon characterization of quantum optoelectronic devices. The successful candidate will contribute to cutting-edge research in quantum photonics, single-photon technologies, and next-generation semiconductor devices.
Key Responsibilities:
Lead the installation, commissioning, calibration, and optimization of a state-of-the-art single-photon-emission characterization platform together with ultrafast and time-resolved optical instrumentation.
Develop, implement, and continuously improve advanced optical measurement methodologies, including photoluminescence (PL), electroluminescence (EL), time-correlated single-photon counting (TCSPC), Hanbury Brown-Twiss (HBT) interferometry for g²(0) measurements, fluorescence lifetime analysis, and quantum efficiency characterization.
Investigate fundamental carrier transport, exciton formation, recombination dynamics, photon antibunching, emission coherence, Purcell enhancement, and light-matter interactions to establish performance-limiting mechanisms and guide device optimization.
Publish research findings in leading international journals and present results at prestigious international conferences.
Contribute to competitive grant proposals, technical reporting, project management, equipment procurement, laboratory management, and compliance with laboratory safety regulations.
Mentor graduate students, research assistants, and junior researchers, while fostering a collaborative and innovative research environment.
Job Requirements:
PhD in Electrical Engineering, Materials Science, Applied Physics, Optical Engineering, Photonics, Physics, or a related discipline.
Strong hands-on experience in optical and electrical characterization of semiconductor/optoelectronic devices, including PL, EL, spectroscopy, and time-resolved measurements.
Experience in designing, setting up, commissioning, and operating advanced ultrafast optical instrumentation and characterization systems.
Experience with TCSPC, FLIM, transient absorption spectroscopy, quantum yield measurements, and single-photon characterization techniques (including g²(0) and HBT interferometry) is highly desirable.
Knowledge of quantum optoelectronics, quantum light sources, excitonic materials, colloidal quantum wells, quantum dots, optical cavities, or integrated photonic devices is an advantage.
Strong publication record in high-impact peer-reviewed journals with excellent scientific communication and technical writing skills.
Ability to work independently and collaboratively in multidisciplinary research teams, with strong analytical, problem-solving, and interpersonal skills. Knowledge of quantum optoelectronics, excitonic devices, or single-photon sources is an advantage.
Proven track record of high-quality publications and strong scientific communication skills.
Demonstrated experience independently designing, setting up, and operating ultrafast/time-resolved optical instrumentation, including fluorescence lifetime imaging microscopy (FLIM), transient absorption spectroscopy, TCSPC-based lifetime studies, and quantum yield measurement systems, is highly valued.
