• Develop and optimize iterative synthesis protocols for growing high-quality diamond single crystals

• Perform materials characterization using Raman spectroscopy, Atomic Force Microscopy (AFM), X-ray diffraction (XRD), and scanning electron microscopy (SEM) to establish quality feedback loops

• Execute post-synthesis hydrogen termination processes via plasma hydrogenation

• Conduct surface and electrical characterization of hydrogenated diamond including sheet resistance measurements and crystal face specificity analysis

• Verify hydrogenation effectiveness and optimize process parameters for crystal quality improvement

• Maintain detailed experimental records, technical documentation, and equipment operation logs

• Prepare progress reports and technical presentations for project review meetings

• Collaborate with device fabrication team to ensure material specifications meet device requirements

Job Requirements:

• PhD degree in Materials Science, Physics, Chemistry, Chemical Engineering, or related field with specialization in diamond synthesis, semiconductor materials, or advanced crystal growth techniques

• Minimum 3 years’ experience in chemical vapor deposition (CVD), preferably with diamond or wide-bandgap semiconductors

• Hands-on expertise with MPCVD or similar plasma-assisted CVD systems, including understanding of plasma chemistry, gas handling, and vacuum systems

• Strong background in materials characterization techniques including Raman spectroscopy, AFM, XRD, and SEM with ability to interpret complex spectroscopic and microscopic data

• Experience with surface chemistry, hydrogen plasma treatments, or surface functionalization of semiconductors is highly desirable

• Knowledge of semiconductor device physics and electronic-grade material requirements

• Proficiency in experimental design, data analysis, and statistical methods for process optimization

• Good writing skills for writing proposals, reports and publications in good academic journals

• Strong organizational and project management skills with ability to meet deliverable deadlines

• Ability to work independently while collaborating effectively in a multidisciplinary, multi-institutional team environment

• Experience with safety protocols for high-temperature systems, reactive gases, and vacuum equipment

• Prior experience with diamond synthesis or wide-bandgap semiconductors (SiC, GaN) is a strong advantage
