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
