A facile post-peeling modification approach of elastic dielectrics for high-performance conformal organic thin-film transistors

Abstract

Conformal organic thin-film transistors (OTFTs) that can adhere seamlessly to human skin or within the body are highly desirable for future large-scale low-cost wearable and implantable electronics. However, the fabrication of high-performance elastic dielectric-based conformal OTFTs is still a huge challenge, because it is difficult to directly deposit high-quality organic semiconductor thin films on elastic dielectrics. Here, a facile post-peeling modification approach is developed to functionalize the surface of elastic dielectrics and realize high-performance conformal OTFTs. The maximum hole and electron mobilities are respectively as high as 5.48 cm2 V−1 s−1 and 1.03 cm2 V−1 s−1, which are remarkably superior to all the reported values for elastic dielectric-based OTFTs. This functionalization approach significantly promotes the crystallinity and crystallite size of organic semiconductor thin films on elastic dielectrics, and paves the way for the fabrication of high-performance conformal and stretchable skin electronic devices.
