Geometry dependent performance limits of stretchable reduced graphene oxide interconnects: The role of wrinkles

Computational study of the water-driven graphene wrinkle life-cycle towards applications in flexible electronics

“…Additionally, the In–Ga–Zn–O (IGZO), pentacene, reduced graphene oxide(rGO), and rGO/ Polydimethylsiloxane(PDMS) based TFTs are observed to preserve the electrical performance and mechanical stability under the strain of 20% due to wrinkles’ existence 18 – 21 . Similar behavior was observed in silver, and rGO based interconnects 17 , 18 , 22 It inspired the investigation of dependency of the device performance on individual geometrical parameters of the wrinkles. In an IGZO TFT and rGO interconnect, the wrinkles’ wavelength and amplitude were controlled in a way so the device can be bent up to 13 μm and strained up to 5% while preserving the electrical performance 17 , 23 , 24 .…”

Nirmalraj et al 25 had demonstrated controlling the Pentacene growth on a MoS 2 substrate by tuning the wrinkle height.…”

“…For example, Raghav et al had studied the wedging of a graphene bilayer by water molecules 14 . The first on-purpose fabrication of the wrinkles was demonstrated in 2011 15 , followed by multiple studies on modeling the wrinkle theoretically/numerically 11 , 16 , 17 .…”

Stretchable Ink Printed Graphene Device with Weft-Knitted Fabric Substrate Based on Thermal-Acoustic Effect

“…When the sample is stretched for 4000 cycles, and the strain is released to 0%, the layers overlap in most areas. Although the irreversible reaction stems from the local delamination of the stressed microstripes of rigid materials after the spread of the fracture according to morphology studies, some previous experiments have demonstrated that the layered graphene design enhances the functionality of stretchable devices. , …”
