Decrease of threshold voltage (Vth) for single-layer ITO/PBO + MWNT/Al LEDs as MWNT content increased
Current–voltage response of single-layer ITO/PBO + MWNT/Al light emitting diodes.
Electroluminescence emission spectra of single-layer ITO/PBO + MWNT/Al
light emitting diodes at a bias voltage of 9 V as a function of MWNT content.
current increased by about two orders of magnitude over those of the diodes without MWNT
