The LUMINOUS! Centre of Excellence for Semiconductor Lighting and Displays at NTU is seeking a Research Fellow (Quantum Optoelectronic Devices & Single-Photon Diodes) to support an NRF-funded project on electrically driven single-photon-emitting diodes based on colloidal quantum wells. The role involves device fabrication, optical-cavity integration, and advanced electrical/optical 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:

• Fabricate and process CQW-based optoelectronic devices, including LEDs and electrically driven single-photon diodes (SPDs), using cleanroom nanofabrication techniques (thin-film deposition, lithography, etching, encapsulation).

• Integrate optical cavities (e.g., DBR cavities) with CQW emitters to enhance spontaneous emission via the Purcell effect.

• Perform electrical, optical, and single-photon characterization, including photoluminescence (PL), electroluminescence (EL), time-correlated single-photon counting (TCSPC), and g²(0) measurements.

• Support orientation control and positioning of individual CQWs for deterministic coupling to optical resonators.

• Investigate carrier dynamics and emission coherence in optically and electrically driven single-photon devices.

• Collaborate with PI, researchers, and students on device development, data analysis, and interpretation.

• Prepare high-impact journal publications, conference papers, and technical reports.

• Assist in project execution, reporting, laboratory safety, and mentoring of junior researchers.

Job Requirements:

• PhD in Electrical Engineering, Materials Science, Applied Physics, or related fields.

• Strong hands-on experience in semiconductor device fabrication, particularly LEDs and nanoscale optoelectronic devices.

• Experience with cleanroom nanofabrication (thin-film deposition, lithography, etching).

• Familiarity with optical cavities, resonators, or photonic structures is highly desirable.

• Experience in optical and electrical characterization, including PL, EL, spectroscopy, and time-resolved measurements.

• 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.
