Abstract
NPB surface morphologies deposited on different temperature substrates were investigated using atomic force microscopy(AFM). That the NPB morphology turned from island morphology at high temperature (100°C) to grain morphology at room temperature was found. To characterize the effect of NPB surface morphology, the devices with the structure of Glass/ITO/NPB/Alq3/Al were fabricated using NPB films deposited at different substrate temperature and their performances were compared.
