Research Scientist (Diamond Device Fabrication and Electrical Characterization) Full-time

Research Scientist Position

Temasek Laboratories@NTU (TL@NTU) is a premier research institute at Nanyang Technological University specializing in advanced defense and security technologies. The institute collaborates with external partners and stakeholders on cutting-edge research in strategic defense systems, advanced materials, power electronics, and semiconductor technologies. TL@NTU houses state-of-the-art cleanroom facilities, thermal evaporation systems, and electrical characterization equipment supporting mission-critical research initiatives. We are seeking a Research Scientist to lead device fabrication and electrical characterization for developing diamond-based semiconductor devices for next-generation defense electronics.

Key Responsibilities:

• Lead the development and optimization of surface charge transfer doping techniques for hydrogen-terminated diamond crystals through thermal evaporation of transition metal oxide (TMO) films
• Design and execute metal oxide deposition processes with optimized parameters to achieve effective charge transfer while maintaining diamond surface conductivity
• Implement in-situ annealing protocols for effective metal oxide film deposition and formation of 2-dimensional hole gas (2DHG) channels
• Fabricate low-resistance ohmic contacts through cleanroom processes for integration into high-performance electronic devices
• Conduct comprehensive electrical characterization including sheet resistance measurements, I-V characterization, and transport property analysis
• Verify and optimize the surface transfer doping mechanism and characterize diamond post-deposition to ensure maintained conductivity
• Perform cleanroom fabrication processes including photolithography, etching, metallization, and device patterning
• Develop processes for integrating diamond-based devices such as Radiofrequency (RF) field effect transistors (FETs) and high-power electronic devices
• Coordinate safe transport of diamond wafers between fabrication facilities and ensure adherence to project timelines
• Collaborate with materials synthesis team to provide feedback on material specifications and device requirements
• Maintain detailed fabrication protocols, process documentation, and device characterization records
• Prepare comprehensive technical reports and presentations for project deliverables and review meetings

Job Requirements:

• PhD degree in Electrical Engineering, Materials Science, Physics, Applied Physics, or related field with specialization in semiconductor device fabrication and characterization
• Minimum 3 years of relevant experience in cleanroom device fabrication, preferably with wide-bandgap semiconductors or novel electronic materials
• Extensive hands-on experience with cleanroom processes including photolithography, thin film deposition (thermal evaporation, sputtering), etching, and metallization
• Strong expertise in electrical characterization techniques including I-V measurements, C-V profiling, Hall effect measurements, and device parameter extraction
• Knowledge of metal oxide thin film deposition and surface functionalization of semiconductors
• Experience with ohmic contact formation and contact resistance measurement techniques
• Understanding of semiconductor device physics, particularly field-effect transistors, surface conductivity mechanisms, and charge transfer processes
• Proficiency in device simulation tools and electrical measurement equipment (probe stations, parameter analyzers, etc.)
• Experience with diamond, SiC, GaN, or other wide-bandgap semiconductor devices is highly desirable
• Good writing skills for writing proposals, reports and publications in good academic journals
• Strong project management and organizational skills with demonstrated ability to meet strict deadlines
• Ability to work independently while collaborating effectively across multidisciplinary teams and multiple institutions
• Rigorous adherence to cleanroom protocols, safety procedures, and contamination control practices
• Prior experience with RF devices, power electronics, or high-voltage devices is an advantage
