The Faculty of Science and Leiden Institute of Physics (LION) have a vacancy for

2 PhD Positions // Quantum transport in van der Waals heterostructures

Vacancy number: 22-526

Are you a highly-motivated aspiring PhD students interested in pursuing cutting-edge experimental research in the area of quantum transport in an der Waals heterostructures? Are you interested in asking fundamental questions in the area of emerging quantum states driven by proximity effect? We have openings for 2 PhD positions at Dr. Semonti Bhattacharyya’s group in Leiden Institute of Physics (LION).

Exfoliation of graphene, followed by other layered materials have ushered in a new era of experimental physics, where designer new hybrid materials can be created by pick-and-drop van der Waals assembly of 2D materials with completely different properties. Recently, it has been discovered that properties of such heterostructures can be tuned by introducing a twist angle between two van der Waals materials.

Van der Waals stacking is a unique route to create defect-free, smooth interface between to materials with completely different properties. Hence, these type of assemblies are ideal fertile ground to study mechanisms of proximity effect and interaction different quantum phases without the presence of significant amount of disorder. However, understanding and harnessing of such proximity effects and interaction are at a nascent stage. The PhD research topic involves (i) experimental detection and (ii) manipulation of new emergent quantum phases in such hybrid heterostructures as a function of twist angle and pressure. Experimental techniques will involve van der Waals stacking, nanofabrication, and low temperature magnetotransport measurements.

About Us
We are a newly established group at Quantum Matter & Optics group, Leiden University. Leiden University is the birthplace of superconductivity and home to Kamerlingh Onnes, Lorentz, Huygens, Einstein, de Sitter, and others (see e.g. the wall of signatures from Ehrenfest lecturers).

The Faculty of Science is a world-class faculty where staff and students work together in a dynamic international environment. It is a faculty where personal and academic development are top priorities. Our people are committed to expand fundamental knowledge by curiosity and to look beyond the borders of their own discipline; their aim is to benefit science, and to make a contribution to addressing the major societal challenges of the future.

The research carried out at the Faculty of Science is very diverse, ranging from mathematics, information science, astronomy, physics, chemistry and bio-pharmaceutical sciences to biology and environmental sciences. The research activities are organised in eight institutes. These institutes offer eight bachelor’s and twelve master’s programmes. The faculty has grown strongly in recent years and now has more than 2.300 staff and almost 5,000 students. We are located at the heart of Leiden’s Bio Science Park, one of Europe’s biggest science parks, where university and business life come together.

Terms and conditions 
The starting date is flexible, and the PhD program in the Netherlands takes 4 years.

We offer a  full-time 1 year term position for initially one year. After a positive evaluation of the progress of the thesis, personal capabilities and compatibility the appointment will be extended by a further three years. Salary range from 2.541,-  to €3.247,-  gross per month (pay scale P in accordance with the Collective Labour Agreement for Dutch Universities).

Leiden University offers an attractive benefits package with additional holiday allowance (8%) and end-of-year bonus (8.3 %), training and career development and sabbatical leave. Our individual choices model gives you some freedom to assemble your own set of terms and conditions. Candidates from outside the Netherlands may be eligible for a substantial tax break.

All our PhD students are embedded in the Leiden University Graduate School of Science. Our graduate school offers several PhD training courses at three levels: professional courses, skills training and personal effectiveness. In addition, advanced courses to deepen scientific knowledge are offered by the research school.

Leiden University is strongly committed to diversity within its community and especially welcomes applications from members of underrepresented groups.
