Crystal Growth Scientist

Job Title: Crystal Growth Scientist (VGF Method - GaAs)

Location: China

Position Overview

We are seeking a highly skilled Crystal Growth Scientist with expertise in Gallium Arsenide (GaAs) crystal synthesis using the Vertical Gradient Freeze (VGF) method. The ideal candidate will possess a strong background in physics and hands-on experience with semiconductor crystal growth across various techniques. You’ll be joining a dynamic team driving innovations in compound semiconductor materials for high-performance electronic and optoelectronic applications.

Key Responsibilities

• Conduct and optimize the growth of high-quality GaAs crystals via the VGF method.
• Develop and refine thermal profiles, crucible configurations, and ambient conditions to ensure consistent crystal quality and yield.
• Collaborate with R&D teams to analyze crystal defects and improve process parameters.
• Utilize characterization techniques such as XRD, SEM, and Hall measurements to assess material quality.
• Author technical documentation and support production scaling efforts.
• Maintain lab equipment and ensure compliance with safety and cleanroom protocols.

Qualifications

• Ph.D. or Master’s degree in Physics, Materials Science, or related field.
• Proven experience in crystal growth for semiconductors (VGF, LEC, CZ, MBE, CVD, or other methods).
• Deep understanding of thermodynamics, phase diagrams, and solid-state physics.
• Familiarity with GaAs and III-V compound materials is preferred.
• Strong analytical and problem-solving skills with hands-on lab experience.
• Fluent in English; Mandarin is a plus but not required.

Preferred Traits

• Innovative mindset with a drive for continuous process improvement.
• Excellent communication and team collaboration abilities.
• Prior experience working in a multinational or cross-cultural environment.

What We Offer

• Competitive compensation and benefits.
• Opportunity to work on cutting-edge materials research.
• Supportive team culture and career development pathways.
