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 classical (light) optics for electron beams by developing reconfigurable phase plates (PPs). 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 its electron-optical functionality to match a given set of sample and experimental conditions. This will optimize the performance of the microscope thereby enhancing our ability to extract quantitative physical information from the data. Your primary tasks will be to design, characterize, implement and finally utilize the adaptive optics devices. You will work in close cooperation of the Metamaterials group of the DTU Department of Electric and Photonics Engineering (DTU Electro) and DTU Nanolab for their fabrication and characterization.

You will be based in the Metamaterials group headed by Associate Professor Andrei Lavrinenko, who will be your main supervisor, but you will also closely interact with DTU Nanolab, working with Assistant Professor Ada-Ioana Bunea and Affiliated Associate Professor Marco Beleggia, who will be your co-supervisors. The project will include an external stay at the University of Modena, Italy, in the group of Professor Stefano Frabboni.

Responsibilities and qualifications
Your primary responsibility will be to design phase plates for electron beams capable of tuning the beam characteristics under external applied voltage. The design stage will proceed in three steps: 1) simulation of the electric field produced by a designed configuration, 2) calculation of the effects of this field on an electron beam passing through the device, 3) prediction of the arising from the shaped beam interacting with a given sample of interest. After the fabrication of samples (this is the main task of the 2nd PhD position in ADELE, which will be carried out primarily at DTU Nanolab), your task will be to assess the devices performance once implemented into a transmission electron microscopy setup. Therefore, qualified prerequisites for this position are 1) expertise in analytical/numerical modelling of electromagnetic fields and electron-optics, 2) knowledge of electron-matter interactions, and 3) practical experience with Scanning and Transmission Electron Microscopy.

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 .

Assessment
The application will be assessed by Associate Professor Andrei Lavrinenko, Affiliated Associate Professor Marco Beleggia and Assistant Prof. Ada-Ioana Bunea.
