Organometal halide and all-inorganic perovskite semiconductors have recently emerged as highly promising and inexpensive materials for solar cells, photodetectors, displays, and lasers. This rapid advancement has become possible due to their remarkable optoelectronic properties (direct bandgap and high absorption coefficient, sharp optical band edge, defect tolerance, high ambipolar carrier mobility) coupled to facile low-temperature processing such as spin-coating. ULTRA-LUX project and this work have the ambition to enable high-brightness perovskite-based light-emitting diodes and injection lasers.
So far, the standard technology for perovskite LEDs involves organic-based transport materials to provide carrier-selective transport towards the emissive zone. It is well-acknowledged that a fully inorganic light-emitting device can sustain higher current density operation without degradation. The remaining challenge is to achieve similar high performance with these inorganic functional layers.
The selected candidate will be conducting a thorough experimental work to optimize layers processing conditions and their properties (doping level, thickness, morphology). Although we have already demonstrated high-performance inorganic device stacks, further improvements are necessary to help the technology reach its full potential. Experimental techniques include fabrication of perovskite LEDs in cleanrooms and wet labs using various deposition techniques (spin-coating, evaporation, sputtering); optical and electrical characterizations (AFM, SEM, J-V-L, photoluminescence, C-V, XRD, UV-VIS); cleanroom integration activities (lithography and patterning).
