PhD Position Pushing MEMS Resonators to Their Physical Limits TU Wien in Austria

The Institute of Sensor and Actuator Systems (ISAS) at TU Wien, led by Prof. Ulrich Schmid, is offering a PhD position focused on pushing MEMS resonators to their physical limits for next-generation timing applications. This opportunity is part of the TrueTime project, a collaborative effort with industrial partners, aiming to advance the scientific and technological foundations for timing devices using silicon carbide (SiC) and polycrystalline diamond (PCD), surpassing the intrinsic limits of silicon (Si).

TU Wien, located in Vienna's vibrant city center, is a leading research university known for its commitment to excellence in both basic and applied research. The ISAS group values open communication, curiosity, and teamwork, providing a supportive environment with excellent infrastructure and technical resources. The project is scheduled to start in July 2026, and the successful candidate will work under the guidance of Prof. Ulrich Schmid and Dr. Andre Loch Gesing.

The research will focus on designing and fabricating MEMS resonators in Si, SiC, and PCD, utilizing cleanroom techniques such as lithography, etching, and metallization. The candidate will conduct electrical and optical characterization of these resonators, collaborate with a postdoctoral researcher for multi-physics modeling, and engage with industrial partners. The role also includes attending scientific conferences and contributing to scientific publications.

The position offers a 3-year PhD contract, with an initial 1-year term followed by an internal evaluation for potential extension. Remuneration is based on the Austrian collective agreement for university staff, amounting to EUR 2,926.48 gross/month (14 times a year) for 31 hours/week, totaling 40,970.69 €/Year. Additional benefits include continuing education, flexible working hours, and a central workplace with excellent accessibility.

Applicants must have an MSc or equivalent degree in electrical or mechanical engineering, physics, or a related field. Essential qualifications include a strong interest in experimental work, hands-on cleanroom experience, device fabrication, and high-frequency electrical characterization. Good English communication skills are required, and prior knowledge of micro- and nanofabrication or thin film deposition/analysis is advantageous but not mandatory. The selection process emphasizes analytical thinking, curiosity, and independence.

The application process consists of three stages: (1) submission of a single PDF file (motivation letter, CV, transcripts, diploma) to [email protected] by May 15th, 2026; (2) first interview and completion of two research exercises for pre-selected candidates; (3) second interview and final selection. TU Wien encourages applications from women and individuals with special needs, offering preferential consideration to equally qualified female candidates.
