10 PhD Positions in Optoelectronic Semiconductors Semiconductor materials are the cornerstone of modern electronic and photonic technology, and central to sustainable economic growth. So far, the functions of semiconductors are mainly defined by chemical and physical properties of their components, and organic and inorganic semiconductors are treated as separate research areas. We want to overcome the divide in material systems and tailor unprecedented optoelectronic properties by the International German-Australian Research Training Group: Optical excitations in organic and inorganic semiconductors (OPTEXC) - Understanding and control through external stimuli The University of Bayreuth (Germany), the University of Melbourne (Australia) and Monash University (Australia) together have constituted an interdisciplinary International Research Training Group in the areas of experimental and theoretical physics, synthetic, physical and computational chemistry, electrical engineering, material sciences and related areas. We are looking for highly talented, passionate graduate students (m/f/d) with excellent track records interested in pushing forward our understanding of nature and its application in technology. The project builds on our established, supportive scientific network and includes research stays at a German and an Australian partner, leading to Joint PhDs with degrees from two universities. The topic areas are Controlling decoherence in the singlet fission process. Exciton delocalization and dissociation in non-entangled conjugated bottlebrushes and polyelectrolytes. Control exciton delocalization by shear-induced alignment. Controlling anisotropy in lead-free perovskite analogues by pressure treatments for efficient sustainable solar cells. Photo-switchable quantum dot-dye arrays for exciton logic gates. Nearfield-control of excited state dynamics. Unravelling Light-Matter Interactions in nano- and micro-patterned perovskite films and devices. Please send your application before January 7, 2025 as a single PDF file of less than 10 MB to application.optexc@uni-bayreuth.de. If you are excited about excitons, further information on the International Research Training Group, the underlying scientific projects and the application process are available on our website www.optexc.uni-bayreuth.de. Application deadline 7 January 2025. The positions are fully funded for minimum of three years: TV-L E13 75% (Joint PhD with 2 years Bayreuth, 1 year Melbourne) or equivalent PhD stipend (2 years Melbourne, 1 year Bayreuth)
