“…Understanding the origin of these structures emerging from uniform states and identifying the role of mechanical forces in this process is one important aspect of morphogenesis. Controlling the length-scales characterizing these structures allows the fabrication of versatile patterns for applications in optics, 37 microuidics, 38 stretchable electronics [39][40][41][42] or for metrology in nanometric lms.…”

Wrinkle to fold transition: influence of the substrate response

Spatially confined rigid membranes reorganize their morphology in response to imposed constraints. Slight compression of a rigid membrane resting on a soft foundation creates a regular pattern of sinusoidal wrinkles with a broad spatial distribution of energy. For larger compression, the deformation energy is progressively localized in small regions which ultimately develop sharp folds. We review the influence of the substrate on this wrinkle to fold transition by considering two models based on purely viscous and purely elastic foundations. We analyze and contrast the physics and mathematics of both systems.

“…At the first stages of the fabrication of OLEDs by Philips, the devices consisted of simple structures of poly(dialkoxy-p-phenylenvinylene) (dialkoxy-PPV) that were situated between a metallic electrode and tin-doped indium oxide (ITO) as the transparent conductive layer [8]. Glass is extensively used as a substrate to fabricate this type of LED, while polyethylene terephthalate (PET) can also be used for fabrication of flexible devices [9,10].…”

“…[1][2][3][4][5][6][7][8] However, indium-tin oxide (ITO), the most widely used electrode in OLEDs, has a very poor tolerance to external mechanical stress. 9 Furthermore, its cost has increased gradually owing to a scarcity of indium.…”

Ultimate flexible organic light-emitting diodes (OLEDs) should have an ultra-high device efficiency, a low-efficiency roll-off at a high luminance and excellent flexibility. Here, we realized flexible tandem OLEDs using a graphene anode with a very high electroluminescent efficiency of~205.9 cd A − 1 , 45.2% (~396.4 cd A − 1 , 87.3% with a hemispherical lens) and a very low efficiency roll-off at a high luminance of~6.6% at 10 000 cd m − 2 (~3.8% with a hemispherical lens) by stacking two organic electroluminescence (EL) units. For the first time, we used an easily controlled and low-temperature processable charge generation layer with lithium nitride (Li 3 N). This simultaneously provided efficient stacking of EL units and enhanced compatibility of the flexible device on a thin plastic substrate. The flexible tandem OLEDs with a graphene anode also showed great flexibility against bending up to a bending strain of 6.7%. These results represent a significant advancement towards the production of next-generation flexible displays and solid-state lighting that use a graphene anode.
