Organic transistors. So we have optical transistors and perovskite transistors, why not organic transistors? Apparently the point of "organic" transistors is flexibility and biocompatibility, which means the ability to implant it in your body and not have your body reject it, and not performance, but these researchers have found a way to improve performance anyway. They've gotten their "complementary vertical organic transistor technology" (whatever that is) which could switch at megahertz speeds to switch at gigahertz speeds.
I don't know how this "complementary vertical organic transistor" is made and the paper is paywalled, but judging from the abstract the physics might be beyond my understanding anyway. It has currently been demonstrated only in very simple circuits (complementary inverters and ring oscillators), not full-fledged computing devices. The article says "With this new technology they are just a stone's throw away from the commercialization of efficient, flexible and printable electronics of the future" but it is surely a long way from commercialization.
