Experimental results show that cracks originate from the localized deformation regions associated with aligned grain boundaries. Microscopical observations suggest that the alignment of the grain boundaries is caused by local grain boundary sliding and grain rotation, which resulted in the in-plane and out-of-plane cooperative movements of the grains in the multilayers. From the localized damage regions, shear fracture in the through-thickness direction occurred in the nanoscale Cu/Ta multilayer. ©2006 American Institute of Physics Origin of cracking in nanoscale Cu/Ta multilayers GP Zhang XF Zhu J Tan Y Liu doi:10.1063/1.2244015 Applied Physics Letters, Vol. 89, No. 4.

The concept of our flexible OLED design is based on integration of a TOLED structure on an aluminum-laminated polyethylene terephthalate (Al-PET) substrate. Microcavity TOLEDs were formed for color tuning and efficiency enhancement. For a flexible TOLED with a 110-nm-thick poly (p-phenylenevinylene) light-emitting layer, it exhibited a luminous efficiency of 4.6 cd/A at 10 V. The performance of a TOLED made on a plastic substrate is analyzed and compared with that of the identical device on a rigid glass substrate. It is demonstrated that the flexible TOLED on Al-PET foil can be bent to a substantial degree without breaking.
