The European Research Council (ERC) has granted a five-year project,

Atomic Insight Cavity Array Reactor, (ATOMICAR) with the aim to finally start to answer the ultimate question in nanoparticle catalysis:

How, in atomic detail, does the catalytic reaction happen on the nanoparticles?

In order to address this question experimentally, it is necessary to quantitatively measure the catalytic conversion of single, isolated nanoparticle under relevant reaction conditions which requires an unprecedented sensitivity of about 1000 chemical turnovers/s or better. This goal will be achieved via indirect measurement of the reaction rate in a “cavity array reactor chip”.

You will be part of a dedicated team working towards this goal.

Your main task will be help build and operate a (2D)scanning laser interferometric setup to measure mechanical vibrations of suspended graphene films (MHz frequency). You will use this tool to scan a large array of small, sealed reactors and measure their internal chemical conversion.

The work will be headed by Professor Peter C.K. Vesborg and will mostly be carried out at DTU-Physics is in the section for Surface Science and Catalysis (Surfcat), but some of the work will be done at DTU-Danchip and CEN (DTU’s facilities for MEMS fabrication and electron microscopy).

Qualifications
You have a PhD degree in engineering, physics, chemistry or materials science.

You have significant experience with building and operating opto-mechanical systems such as scanning Raman microscopes, optical tomography microscopes or similar.

Experience with handling graphene (graphene transfer) or other 2D materials is also a very significant advantage.

Experience with catalytic measurements, UHV/surface science and TEM is also a bonus.

The ATOMICAR project is a team effort so you must be a team player besides being highly motivated, hard-working and independent. Excellent written and spoken English skills are mandatory.

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and terms of employment
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed with the relevant union.

The workplace is the department of physics at DTU’s Lyngby campus and the position is for 24 months. Employment should preferably start before the end of 2019, but a later start might be possible.
