Postdoctoral Researcher Position in Epitaxial Growth of III-Nitrides

Electronics Integration and Reliability (EILB) is a research group at Aalto University School of Electrical Engineering focused on exploring innovative materials and design concepts for advanced electronics. We are developing high-efficiency, sustainable semiconductor substrates and devices for power electronics, RF, and smart sensor applications. Our mission is to achieve transformative device innovations by leveraging high crystal quality and single crystal aluminum nitride (AlN) thin film-based technologies.

We are seeking a Postdoctoral Researcher with strong expertise in the epitaxial growth and characterization of III-nitrides. In this role, you will contribute to various ongoing projects in the group, covering topics such as thermally conductive Silicon on Insulator (SOI), AlN polarization-doped field effect transistors, AlN on Si for single photon emitters and RF filters, and vertical wall-grown AlN for 3D-MEMS applications.

Key Responsibilities:

• Grow high-quality III-nitride thin films using techniques such as metal-organic vapor phase epitaxy (MOVPE).

• Develop and optimize epitaxial processes to enhance crystal quality and performance.

• Conduct thermal, electrical, and microstructural characterization of grown samples to evaluate material and device properties.

• Collaborate with international partners and contribute to several EU-funded projects, gaining valuable exposure to European research in electronic components and systems.
   

Requirements:

• Doctoral degree in a suitable area (e.g. electrical engineering, physics, or materials science)

• Hands-on experience and solid understanding of epitaxial processes, ideally in MOVPE or MBE

• A strong track record of research in III-V or III-Nitride semiconductors

• Experience and solid understanding of relevant characterization methods, such as HRXRD, AFM, Photoluminescence (PL), SEM, and TEM

• Experience on probe-station based measurements for electrical characterization is a plus

• Experience in micro- and nanofabrication

• Good understanding of semiconductor device physics and WBG semiconductor devices

• Experience in writing grant proposals and securing research funding is an advantage
   

We offer:

• Fixed-term position for 3 years (1+2)

• Opportunity to conduct independent research in OtaNano (OtaNano | Aalto University) using cutting-edge infrastructure in Micronova and Nanomicroscopy Center

• Possibility to participate in already funded public-private-partnership projects, network with major European industrial and academic project partners and contribute to new research funding applications

• Possibility to co-advice graduate students and participate in teaching

• The starting salary for a postdoctoral researcher ranges from 4000-4200 €/month, depending on previous experience

• The contract includes Aalto University occupational healthcare
   

The appointment is available immediately.
