The project focuses on the realization of high performance organic transistors based on the selective grow of organic semiconductor single crystals on organic self assembled monolayers (SAMs). Thereby, two promising approaches should be combined. Self-assembled monolayers (SAMs) can act as capable dielectric layer in transistor devices (enable their low-voltage operation) as well as promotion layer for the crystal grow. Organic single crystals provide improved electrical properties depending on their perfect molecular order. The project aims the investigation of organic complementary circuits based on p- and n-type single crystals selectively grown on corresponding self-assembled monolayers (directly during the device preparation process) to prevent additionally transfer steps.
Final report:
The PhD student Martin Burkhardt attended a kick-off meeting in California in 2008. According to the proposal, samples were shipped to Stanford University and tested in the Bao-labs with first promising results. Approaching a joined public funded project failed, due to the beginning of the financial crisis and change in research focus of the partners. However, after PhD in Germany Martin Burkhardt joined the group of Prof. Michael L. Chabinyc (University of California – Santa Barbara) as consequence of networking during his stay in California. The post-doc position was fully financed by the American partners.
