PhD position on the Data-Driven Development of Novel Piezoelectric Thin Films for Electronic, Photonic and Quantum Technologies Empa in Switzerland

Empa, a leading research institution within the ETH Domain in Switzerland, offers a fully funded PhD position focused on the data-driven development of novel piezoelectric thin films for electronic, photonic, and quantum technologies. The position is based in the Coating Technologies Group at Empa's Laboratory for Surface Science & Coating Technologies, renowned for its expertise in physical vapor deposition (PVD) and innovative thin film research. The project leverages state-of-the-art PVD, high throughput experimentation, and data science to develop thin films with enhanced performance and to discover new functional materials.

The research centers on piezoelectric nitrides, such as AlScN, using reactive high-power impulse magnetron sputtering (HiPIMS). These materials are crucial for technologies like frequency filters in 5G/WiFi communication and micro-electro-mechanical systems (MEMS). The project aims to develop highly efficient piezoelectric thin films and utilize large datasets to advance understanding of synthesis-structure-property relationships in polar nitride materials. The laboratory combines advanced deposition techniques with surface analysis and closed-loop autonomous experimentation, providing a unique environment for interdisciplinary research at the intersection of materials science, physics, and data science.

Applicants should have a master’s degree in physics, materials science, electrical engineering, or a related field, with hands-on experience in thin film deposition and UHV technology. Additional expertise in materials science, piezoelectric/ferroelectric materials, semiconductors, sputter deposition, materials characterization (XRD, XPS, SEM/TEM), lab automation, data science, and python is advantageous. Strong collaboration skills, initiative, systematic work habits, reliability, responsibility, teamwork, and communication skills are essential. Excellent English proficiency is mandatory; German is beneficial but not required.

The position offers a stimulating, international, and collaborative research environment with excellent infrastructure and interdisciplinary opportunities. The PhD is held in collaboration with ETH Zürich, with the candidate working on the Empa Campus in Dübendorf and enrolled in the ETH Zürich doctoral program. The position is available from July 1, 2026, or later by agreement. Empa values inclusion and respect, welcoming applicants interested in innovative, sustainable, and meaningful research activities.

To apply, submit your complete online application—including a letter of motivation, CV, certificates, diplomas, and contact details of two reference persons—exclusively via the Empa job portal. Applications by e-mail or post will not be considered. For more information about the Coating Technologies Group, visit www.empa.ch/ct.
