In the department of Chemistry, division of Molecular Imaging and Photonics, a FLOF-PhD position is available in the Laboratory of Prof. Elke Debroye.
Lead halide perovskites are semiconductor materials with outstanding opto electronic properties, such as broad-range optical absorption and efficient chargetransport, turning them into excellent candidates for application in devices such as solar cells, light-emitting diodes, (X-ray) photodetectors, and sensors.
Most perovskite films for device applications are prepared by a solution spin- coatingprocedure. However, using this method, the final composition and crystalline quality cannot be precisely controlled. The presence of unwanted crystal defects in the perovskite layer induce a rapid decrease in their performance and stability. Moreover, the deposited layers are usually not uniformly covering the entire surface area. This makes it challenging for configuring a device or creating a heterostructure with other materials with the ultimate goal of achieving maximum charge separation and transport properties.
In this PhD, the focus is set on developing deposition strategies for obtaining uniform and highly crystalline perovskite layers with improved optoelectronic performance and stability. Amongst the techniques, chemical vapor deposition will be explored and optimized, followed by rational engineering of a customized device configuration, aiming for the creation of a highly sensitive and stable perovskite-based(X-ray) photodetector. During this process, in-depth and in-situ micro- and spectroscopic studies on both the structure and photo physical properties will be conducted. Lastly, the project scope can be extended toward lead-free perovskites.Profile
You have a master in chemistry. Experience with the synthesis and processing of perovskite materials, and/or chemical vapor deposition, and/or perovskite micro-spectroscopic characterization, and/or photodetector engineering is considered a plus.Offer
FLOF-funding is available for the entirety of the PhD, initially a 1 year contract will be provided which will be extended in case of a good evaluation.Interested?
