PhD position: Nanoelectronics and nanofluidics combined with graphene edge sensors Leiden University in Netherlands

This PhD position at Leiden University focuses on the integration of nanoelectronics and nanofluidics for the development of advanced graphene edge sensors, enabling single molecule detection and biopolymer sequencing. The research is conducted within the Leiden Institute of Chemistry and the Leiden Institute of Physics, under the joint supervision of Dr. Grégory Schneider and Dr. Jan van Ruitenbeek. The project aims to fabricate and characterize devices that leverage the unique properties of monolayer graphene, creating atomically thin readout electrodes embedded in nanofluidic channels. These devices are designed to trap single nucleotides between chemically modified graphene contacts, allowing for direct electrical readout and unprecedented sensitivity and selectivity in molecular identification.

The research addresses current limitations in DNA sequencing technologies, particularly the inability of nanopore sensors to distinguish between similar-sized molecular moieties. By using graphene as transverse electrodes, the project seeks to achieve true base-by-base DNA sequencing and extend applications to protein and polysaccharide sequencing. The device architecture is scalable and tunable, with functionalized graphene edges playing a critical role in sensor performance.

Applicants should have a strong background in nanofabrication, nanoscience, low current device electronics, and graphene or 2D materials devices. Experience with tunneling devices, especially in liquid environments, is highly valued. Candidates must hold an MSc degree in relevant fields such as Chemical Nanoscience, Biophysics, Nanofabrication, Solid-state Physics, Physical Chemistry, Condensed Matter Physics, Nanoscience, or Nanotechnology. Prior experimental work, publication experience, motivation for research, independence, excellent English skills, and teamwork mentality are required.

The position offers a stimulating and collaborative research environment, access to state-of-the-art facilities, and a competitive salary ranging from €3059 to €3881 gross per month. Additional benefits include holiday and end-of-year bonuses, pension scheme, full reimbursement of public transport commuting costs, flexible working hours, generous leave days, options for sabbatical or paid parental leave, home-working allowance, and provision of a laptop and mobile phone. The contract is for one year with the possibility of extension up to four years, culminating in a PhD thesis. The candidate will also contribute to classroom teaching and supervise BSc and MSc research projects.

Leiden University is renowned for its international research excellence and commitment to personal and academic development. The Faculty of Science offers a dynamic environment with diverse research activities and strong ties to local and international research groups. The university values inclusivity, diversity, and the creation of a supportive community for all staff and students.
