The idea of the project is to develop new organic semiconductors for photodetectors. The molecular design of these materials is based on a donor-acceptor strategy that selects rigid and flat fragments. The developed compounds will have intramolecular charge transfer and absorption in the visible/near-infrared regions of the spectrum. As a result of the planarity and rigidity of the compounds, nondispersive carrier transport and high carrier mobility are expected.
Project funding:
Projects funded by the Research Council of Lithuania (RCL), Projects carried out by researchers’ teams
Project results:
The most promising compounds will be tested in devices having multilayered diode or vertical permeable base transistor structures. The thickness and composition of the active layers will be optimized to get maximum gain from the photodetectors. Furthermore, the research of new fabrication methods will be developed to obtain devices with a detection spectrum of less than 60 nm at maximum half and an external quantum efficiency of more than 100%.
Period of project implementation: 2022-07-01 - 2025-06-30
