Job beskrivelse

If you aim at scientific excellence and want to establish a career as a scientist within the fields of electron optics and nanotechnology, then we have the ideal opportunity for you! Join us and be a part of the new ‘ADaptive optics for ELEctron beams (ADELE)’ project supported by the Danish Research Counsel (Project DFF-2). The main objective of ADELE is to implement adaptive optics ideas from the classical (light) optics for electron beams by developing reconfigurable phase plates. These are devices that we can use to control precisely the phase of the electron beam, which is crucial to the advancement of electron imaging and spectroscopy techniques for the characterization of nanostructured materials, and of electron beam lithography for nanofabrication. Inspired by the well-established field of light optics, adaptive optics in the context of this project means real-time beam-shaping of the electron beam used as a probe in transmission electron microscopy.

Your PhD project will be an integral part of developing a tunable phase plate that can adapt to a given set of sample and experimental conditions. Your primary tasks will be to develop and implement fabrication protocols for the adaptive optics devices based on designs provided by other ADELE team members. After fabrication, you will also assess the quality of your devices by Scanning Electron Microscopy and other characterization techniques available in the cleanroom. You will carry out your work in close cooperation between DTU Nanolab and the Metamaterials group of DTU Electro, which will be responsible for the design and implementation of the phase plates.

You will be based at DTU Nanolab in the Polymic group headed by Professor Rafael Taboryski, and you will work closely with Associate Professor Marco Beleggia and Assistant Professor Ada-Ioana Bunea, also from DTU Nanolab, and with Associate Professor Andrei Lavrinenko, head of the Metamaterials group at DTU Electro, who will be your co-supervisors. The PhD project will also involve an international stay at the Ernst Ruska Center of the Jülich Research Center, Germany.

Responsibilities and qualifications

Your primary responsibility will be to establish a robust fabrication process for producing phase plates capable of tuning the electron beam characteristics under applied voltage. After fabrication, you will characterize the phase plates in terms of topology, electrical and optical properties. The phase plates will be designed at DTU Electro, while the integration of the fabricated phase plates into a transmission electron microscopy setup will be implemented at the characterization section (electron microscopy facility) of DTU Nanolab. For this project, you should have prior experience with cleanroom fabrication. Experience with e-beam lithography and metal deposition represents an advantage.

You must have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.

Approval and Enrolment

The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU’s rules for the PhD education. https://www.dtu.dk/english/Education/PhD/Rules
