Conducting research for a changing society: This is what drives us at Forschungszentrum Julich. As a member of the Helmholtz Association, we aim to tackle the grand societal challenges of our time and conduct research into the possibilities of a digitized society, a climate friendly energy system, and a resource efficient economy. Work together with around 7,400 employees in one of Europe''s biggest research centers and help us to shape change! Dealing with the challenges imposed by climate change demands the realization of extremely energy efficient hardware for future cognitive and self learning IT systems. This requires disruptive concepts involving new non volatile storage devices from new materials combined with innovative circuit designs to overcome the performance limits of today''s computers. The mission of Peter Grunberg Institute Electronic Materials (PGI 7) (fz juelich.de/de/pgi/pgi 7) is to create a scientific and technological basis for harnessing energy efficient neuromorphic computing inspired by the functioning of the human brain. Two dimensional materials such as graphene and transition metal dichalcogenides (TMDCs) offer high potential for scaling and back end of line (BEOL) integration with CMOS circuits. Together with our partners in the BMBF funded Cluster for Future NeuroSys, phase 2 (neurosys.info), we aim at the wafer scale deposition of 2D materials by means of metal organic chemical vapor deposition. We are offering a PhD Position Deposition and Characterization of 2D Materials for Memristive Devices This position focuses on the deposition and characterization of 2D materials and layers stacks by metal organic chemical vapor deposition using a commercial MOCVD system from AIXTRON SE. The understanding of the growth processes and the layer interaction is crucial for a successful transfer of a full layer stack from the growth substrate to the silicon chip. Your tasks in detail are: Growth studies of 2D layers and layer stacks built from graphene, hexagonal boron nitride, and transition metal dichalcogenides by metal organic chemical vapor deposition on sapphire and related substrates Characterization of the different stages of growth and careful analysis of the layer quality by means of nanoanalytical techniques, such as scanning electron microscopy, atomic force microscopy, Raman and photoluminescence, and photoemission spectroscopy Analysis of the intra and interlayer interactions Optimization of growth towards 2D heterostructures formed from continuous layers with well controlled interfaces Active exchange with collaboration partners Publication of results in peer reviewed scientific journals and presentation at project meetings and conferences Excellent master''s degree in Physics, Chemistry, Material Science, or Electrical Engineering with focus on nanoelectronics technology Profound knowledge of solid state physics, semiconductor physics, and chemical vapor deposition technology Team oriented and highly moti
