The design of high-speed optical memory elements based on organic field-effect transistors comprising [60]fullerene as an n-type semiconductor and 1,3-dihydro-1,3,3-trimethylspiro(2m>Hm>-indole-2,3m>’m>-[3m>Hm>]naphth[2,1-m>bm>][1,4]oxazine) as a light-sensitive component placed at the interface with an aluminum oxide gate dielectric has been developed. The memory elements exhibit a switching coefficient of ∼104 and a minimal programming time of 0.5–1.5 ms.
