Operation co-funded by EU cohesion policy (European Social Fund (ESF)) under the programme EU Structural Funds Investments - LT - ERDF/ESF/CF/YEI (2014LT16MAOP001), managing authority: Finansų ministerija. The source names no beneficiary for this operation. Location: Vilnius County (NUTS LT011); Lithuania. Budget: total eligible expenditure EUR 2,816.33; EU co-financing EUR 2,816.33 (co-financing rate 100%), as stated by the source. Runs 2019-10-11 to 2020-06-30.

Summary from Kohesio (English machine translation by the source): The area of large-area semiconductor devices is experiencing a boom due to promising, intensively researched semi-organic metal halide perovskite materials (normally cubic) for about ten years. The attention of technologists is attracted by the special properties of perovskites: controlled reserve space extending over the entire optical area; high loader agility and diffusion distance; low density of traps; easy-to-install injection molding from solution production technology. The volume perovskite degradable from halide ion migration can be stabilised by inserting separate organic ligands in the initial perovskite solution, forming a stable phase of two-dimensional sheets (2D) of two-dimensional sheets (2D) of a thickness of several elementary cages. Due to spatial quantification, the reduction of the average thickness of the sheets in the 2D perovskite phase increases the gap, so the absorption edge and luminescence move to the area of high energies. There is also a peculiar structure of multiple quantum pits (MQW), which promotes the localisation of exitones in thicker sheets of thinner (higher recombination rate). Recently, the application of perovskite layers to semiconductor laser technologies has been particularly interested. Before creating an active medium for laser radiation, it is important to study the properties of the awakened 2D perovskite radiation amplification. The student will conduct in-depth research: set an excitation threshold for enhanced self-radiation (ASE), external quantum performance during recombination of ASE, linear absorption and dissipation losses, layer degradation of ASE. The results are expected to be used in the student’s final work and published in publications.
