Job description

If you want to design the electronic properties of a material rather than simply measure them, this PhD puts the tools in your hands. When two-dimensional crystals are stacked with a controlled twist, or when a periodic pattern is imprinted into them, an artificial superlattice emerges in which the band structure can be reshaped and bandgaps opened by design, using a novel combination of 2D materials and freestanding oxide membranes.

You will create such materials yourself in a group that has worked with 2D materials for two decades and with full access to the cleanroom and microscopy infrastructure at DTU Nanolab. The project is part of METRIQS and is carried out together with national and international partners.

Responsibilities and qualifications

Your overall focus will be to create and control superlattices in graphene and other 2D materials, and to establish how the engineered structure translates into an engineered electronic band structure. You will pursue two complementary routes: assembling hybrid van der Waals heterostructures in which the moiré periodicity is set by twist angle and lattice mismatch and imprinting periodic patterns directly into the 2D material or its supporting layers by nanofabrication. Both routes call for careful design, reproducible processing and close comparison between intended and realised structure. You will work with colleagues at DTU Physics and DTU Nanolab and with partners in the METRIQS collaboration.

• Design superlattice geometries and device layouts, using modelling and simulation to decide what is worth fabricating.
• Assemble hybrid van der Waals heterostructures from graphene, hBN, transition metal dichalcogenides and related materials with controlled twist and alignment, using a newly developed semi-automatic stacking system, and collect data on stacking recipes and results to obtain and document optimal parameters through datamining and statistics.
• Imprint periodic patterns into 2D materials and their supporting layers using electron beam lithography, etching, thin film deposition and related nanofabrication.
• Fabricate devices in which the engineered materials can be contacted, gated and measured.
• Characterise structure and electronic properties by scanning probe microscopies, electron microscopies, Raman spectroscopy, optical spectroscopy and electrical transport at cryogenic temperatures.
• Connect the measured electronic response back to the intended superlattice design, and iterate on the design.
• Establish reproducible fabrication and measurement protocols, analyse your data and present the results in publications and at conferences.

We are looking for a candidate with a background in physics, nanotechnology, materials science, electrical engineering or a related field. You should have hands‑on experience with micro‑or nanofabrication or comparable experimental laboratory work, and be comfortable with systematic work, data analysis and programming for design, automation or modelling. Experience with 2D materials, layout and CAD design, electron microscopy or electronic transport is an advantage, but the project spans several techniques, and we do not expect you to bring all of them with you. We value curiosity, persistence and the ambition to take ownership of your own project.

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 assessment of the applicants will be made by Professor Peter Bøggild and Timothy John Booth.
