Organic Single-Crystal Transistors and Circuits on Ultra-Fine Au Wires With Diameters as Small as 15 $\mu \text{m}$ via Jigsaw Puzzle Method

A novel jigsaw puzzle method was developed to fabricate the high-performance CuPc and F
₁₆
CuPc organic single-crystal field-effect transistors and circuits on ultra-fine and flexible Au wires with diameters as small as 15 μm. This method weakens the effect of fiber size on the device-fabrication process and provides a simple way to realize organic single-crystal complementary circuits on ultra-fine fibers. The resulting high-performance miniaturized fiber-shaped devices with extremely small diameters have strong potential for the applications in wearable and implantable electronics.
