PhD Student in ferroelectric field effect transistors

Your tasks

• Perform epitaxy and characterization of functional perovskite oxide thin films and their heterostructures
• Establish a composition-structure-function relationship for ferroelectric, semiconducting and metallic materials, together with collaborators
• Grow metal-ferroelectric-semiconductor multilayers, define and optimize lithographic workflows to process the multilayers into device architectures and perform electrical testing and benchmarking of both the individual layers and the multilayer structures as ferroelectric field effect transistors
• Supplement this information with band structure computations towards building a high-performance ferroelectric field effect transistor
• Employ the collected data to publish peer-reviewed articles

Your profile

• Master’s degree or equivalent in materials science, chemistry, physics or a related discipline
• Foundational knowledge on solid state chemistry and/or physics, with knowledge on semiconductors and ferroelectrics considered advantageous
• Understanding of physical vapor deposition and vacuum infrastructure, computational studies of the electronic structure of materials, familiarity with cleanroom device fabrication and experience with Python are considered advantageous
• A communicative and team-oriented profile, who enjoys working in an interdisciplinary research environment
• Professional proficiency in written and spoken English is required; knowledge of German is an asset
