TLDR
Flexible thin-film transistors with excellent thermal stability and their viability for biomedical sterilization processes are demonstrated and are stable even after exposure to conditions typically used for medical sterilization.Abstract:
The excellent mechanical flexibility of organic electronic devices is expected to open up a range of new application opportunities in electronics, such as flexible displays, robotic sensors, and biological and medical electronic applications. However, one of the major remaining issues for organic devices is their instability, especially their thermal instability, because low melting temperatures and large thermal expansion coefficients of organic materials cause thermal degradation. Here we demonstrate the fabrication of flexible thin-film transistors with excellent thermal stability and their viability for biomedical sterilization processes. The organic thin-film transistors comprise a high-mobility organic semiconductor, dinaphtho(2,3- b:2',3'-f)thieno (3,2-b)thiophene, and thin gate dielectrics comprising a 2-nm-thick self-assembled monolayer and a 4-nm-thick aluminium oxide layer. The transistors exhibit a mobility of 1.2 cm 2 V − 1 s − 1 within a 2 V operation and are stable even after exposure to conditions typically used for medical sterilization.read more
