Flexible complementary circuits operating at sub-0.5 V via hybrid organic–inorganic electrolyte-gated transistors
Abstract
Electrolyte-gated transistor (EGT)–based inverter circuits are the basic building blocks of next-generation flexible electronic devices. However, constructing high-performance complementary inverters is challenging due to the unbalanced electrical performances of available p- and n-type EGT semiconducting materials. Here we report high-performance EGT complementary inverters achieved by combining p-type organic electrochemical transistors based on an ion-permeable semiconducting organic polymer and n-type electric double-layer transistors based on an ion-impermeable metal oxide semiconductor. The resulting closely balanced complementary inverters achieve ultrahigh voltage gain (>110) under a low supply voltage of only 0.7 V and have been successfully used to achieve flexible logic circuits and sensitive electrophysiological signal amplification suitable for ophthalmologic diagnostics and measuring eye movement.
