Vertical architecture improves performance of transistor family

Organic electrochemical transistors could be better than conventional inorganic devices for certain uses, but have been held back by performance issues. The solution could be to build up these organic transistors like a sandwich.

Modern electronic gadgets depend on transistors — semiconductor devices that control electrical currents to amplify signals or switch between ‘on’ and ‘off’ states. Most transistors are made of inorganic semiconductors, but organic electrochemical transistors (OECTs) show great promise for certain applications, such as body–machine interfaces and wearable electronics1. However, the development of OECTs has been hindered by problems such as slow switching speeds and low stability during operation2. Writing in Nature, Huang et al.3 start to address these issues by turning conventional OECT architecture on its side.
