Tóm tắt

It is well known that multi-walled carbon nanotubes (MWCNTs) are an excellent nanomaterial. In this paper, the nanocomposite ultra-thin films were fabricated consisting of MWCNTs and poly (3,4-ethylene dioxy thiophene-poly(styrene sulfonate) (PEDOT-PSS) for organic light-emitting diode (OLED). The field-emission scanning electron microscopy (FESEM) images of MWCNTs thin films show that the diameter of MWCNTs are 10-30 nm and their length is 300-500 nm. Electrical and optical properties of the films are investigated and the sheet resistance can reach minimum value at 36.5 Q/sq and the transparency of the film is about 80 percent. The current density-voltage (J-V) characteristics of the devices were also studied.
