Job Description

About the position

Aluminium transition-metal nitrides have emerged as a family of new material that


offers significantly enhanced piezoelectricity and beyond, empowering new acoustic


and electrical functionalities.



This highly collaborative project, jointly investigated by PDI, TU Munich,


University of Münster and HTW-Berlin, is funded by DFG within the priority


programme SPP2477 "Nitrides4Future". The motivation is to realize the transition


from material synthesis to integrated devices for new nitrides, interfacing surface


acoustic waves (SAWs) and nanoelectromechanical systems (NEMS). General aims are:

Incorporation of CMOS compatible transition metals in thin-film synthesis,
gearing towards GHz SAW excitation

Sensoric study of the acousto-NEMS for harsh environments Study of the acousto-NEMS in quantum regime

You will gain comprehensive experience in SAW technology, NEMS/MEMS,


and material science. The project will prepare you for further career advancement


in both industry and academia. You will work under the guidance of experienced


scientists and be provided with cutting-edge research facility.

Your responsibilities

Design of interdigital transducers on new nitrides for the efficient excitation

of high-frequency SAWs (up to 10 GHz). Fabrication of suspended


nanomechanical structures, such as membranes.
Building integrated SAW-nanomechanical systems Characterization and study of physical properties of the integrated devices,

using optical, RF and scanning-probe techniques
Exploring sensing application Communication and collaboration with partner in the project and the network

Your profile

Qualifications:


Master degree in physics or materials science Background in solid state physics Strong motivation, excellent communication and project management capability

Desirable skill set:


Nanofabrication Optical spectroscopy RF measurement Proficiency in English (C1 or equivalent) IT and data analysis skills

Position and salary

This is a full-time position (39 hours per week) with 3 years duration and a tentative


starting date of 01.11.2025. Salary and benefits are according to the Treaty for German


public service (TVöD Bund) to a level of E13-75%.

What we offer

Modern laboratories with a wide range of experimental techniques Supportive environment with experts for various scientific sub-fields International and culturally diverse community Location in the heart of Berlin with excellent public transport connections a subsidized travel ticket Possibility to participate in professional development and/or exchange programs

About PDI

The Paul Drude Institute is part of the Forschungsverbund Berlin e.V. and


member of the Leibniz Association. The institute carries out basic and applied


research at the nexus of materials science, condensed matter physics, and device


engineering.

Inclusive & equal opportunity employer

With approximately 100 employees and more than 15 nationalities, PDI is committed


to building a talented, inclusive, and culturally diverse workforce. We understand that


our shared future is guided by basic principles of fairness and mutual respect.



As an equal opportunity and family-friendly employer, we offer highly flexible employment conditions, such as flexible working hours, parental leave, and home office, and we
