Post-doctoral position

Monolithic III-V single photon detectors

Ref. 2020_042

Project description

The MIND (Materials Integration and Nanoscale Devices) group at IBM Research Europe in Zurich is offering an opportunity for a highly motivated post-doc to work on the development of scaled single-photon devices. The project will be carried out in collaboration with Prof. Kresten Yvind at DTU, Denmark.

The research comprises the design of the detectors, extensive cleanroom fabrication as well as epitaxial MOCVD growth based on Template-Assisted Selective Epitaxy (TASE). The work furthermore involves extensive optical characterization of the fabricated structures at high-speed and/or cryogenic operation in a state-of-the-art optical set-up. The candidate will interact closely with DTU in terms of the design of structures for extreme-dielectric confinement, and the optical design and characterization.

The candidate is expected to hold a Ph.D. degree in physics or electrical engineering with an outstanding academic and publication record and should possess a high degree of motivation and creativity combined with good communications skills in English (spoken and written). Extensive hands-on experience with either advanced device fabrication or broad experience with optical characterization techniques is a mandatory requirement. Existing experience with epitaxial growth is a plus.
