The project concerns study of the electrical properties of two-dimensional materials such as graphene and transition metal dichalcogenides (TMDC). You will fabricate devices using novel ultra-clean dry transfer methods that to a large extend prevent impurities, residues, wrinkles and cracks from compromising the electrical performance of the 2D materials. You will expand and improve our patent-pending identification and assembly system to streamline the fabrication process, and fabricate supported, embedded and suspended 2D devices of the highest quality.
The aims are three-fold: (1) Perfection of 2D material device fabrication, including layered structures, edge contacts and encapsulation. (2) Provide experimental confirmation of theoretical predictions in search of candidates for next generation electronic materials, (3) Study the effect of nanopatterning and processing of TMDC.
The project will be carried out in within the 1 BEuro European project Graphene Flagship, and in collaboration with DTU Centre for Nanostructured Graphene and the Hone group, Columbia University.
Responsibilities and tasks
We offer a 3 year PhD position to perform research in the following areas:
- Fabrication of clean, high performance TMDC devices using beyond state-of-the-art transfer methods.
- Electrical characterization and comparison with theoretical predictions at low to room temperatures.
- Effects of nanopatterning and device processing on electrical characteristics
Candidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in engineering.
Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.
The assessment of the applicants will be made by consideration of relevant, documented experience and competences, here in particular.
- Graphene or TMDC device fabrication
- Low temperature electrical measurements of nanodevices
- Nanopatterning / Electron beam lithography
- Standard characterisation techniques (optical, Raman spectroscopy, TEM).
- Device physics (electronic properties of graphene, 2D materials and van der Waals structures. Role of disorder, doping and contact resistance).
- Software programming and experience with automation/machine vision
We are looking for a student strong in both experimental and theoretical physics, who is creative, fast-learning, independent, hard-working and function well in a team. We will also take into account the past performance in relevant courses (solid state physics, quantum mechanics, transport theory, computational physics, electronics, materials science). It may also count how soon you can start.
The assessment of the applicants will be made Professor Peter Bøggild.
We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world.
Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years.
Further information may be obtained from Professor Peter Bøggild, email@example.com. The project will be co-supervised by Professor Kristian Thygesen, DTU Physics.
