Chicken Albumen Dielectrics in Organic Field-Effect Transistors

The application of the biomaterial dielectrics made of thermally crosslinking natural proteins without any additives in fabricating organic electronics is highlighted. The gate dielectrics of organic field-effect transistors (OFETs) are prepared by the thermal treatment of the chicken albumen film taken directly from a fresh egg. Flexible OFETs and the complementary inverters fabricated with albumen dielectrics are demonstrated.
