Empa is the research institute for materials science and technology of the ETH Domain and conducts cutting-edge research. It is currently searching for a PhD candidate with a strong experimental background in Materials Science, Surface Science or Physical Chemistry to take up a challenging PhD position in the area of Graphene Nanoribbon Science and Technology. Within this PhD project, the electronic properties of atomically precise graphene nanoribbon (GNR) structures will be investigated using surface scientific characterization tools such as scanning tunnelling spectroscopy (STS) and angle-resolved photoelectron spectroscopy (ARPES). A main focus will be set on the investigation of GNRs with zigzag and related edge topologies as well as GNR heterostructures and heterojunctions. These structures will be fabricated in close collaboration with synthesis-related projects. In order to further control the electronic properties of GNRs, various post-growth UHV-based functionalization procedures will be investigated and optimized. In order to link electronic and structural properties with the ultimate resolution, the STS measurements shall be complemented with non-contact atomic force microscopy (nc-AFM) characterization.
Required qualifications include a Master’s Degree in Physics, Chemistry or Materials Sciences. A solid background in Surface Science and previous experience using STM or other UHV surface analysis equipment would be significant benefits. Very good communication skills in English are required, German or French language skills are beneficial. The position is available from November 2015 or upon agreement with a planned duration of 3 years.
