Successful Cooperation of Two Institutes

31 march 2016 г.

A joint project of Institute of Problems of Chemical Physics (Chernogolovka) and Zelinsky Institute of Organic Chemistry has resulted in a new conceptual design of organic field-effect transistors (OFET) developed by Prof. P. Troshin’s team (IPCP) with the use of photo- and electrochromic diarylethene synthesized at ZIOC Laboratory of Heterocyclic Compounds headed by Prof. M. Krayushkin.

These are OFET-based memory elements operating via optically and electrically triggered charge separation between organic semiconductor (fullerene C60) and 1,2-bis(hetaryl)ethene dielectric layers. These devices demonstrate high programming speeds, exceptionally wide memory windows (≈10 V), high switching coefficients of ≈105 at reasonably low operation voltages (3–10 V), and good write-read-erase cycling stability.
