Abstract

Plastic lamination has become a promising approach to the fabrication of high-performance polymeric electronic devices. [T.-F. Guo, S. Pyo, S.-C. Chang, and Y. Yang, Adv. Funct. Mater. 11, 339 (2001)]. The major challenge for achieving high-performance laminated devices is the control of interface quality. In this letter, the various interfaces between two organic films have been investigated using atomic force microscope and impedance spectroscopy. Our results indicate the device performance is directly related to the formation of the interface. We attribute the better charge injection and higher electroluminescence efficiency of a laminated polymer light-emitting diode is due to the nanoscale surface roughness at the laminating interface.
