摘要: The influence of structural ordering methyl cyclohexane appended naphthalene diimide (NMeCy2) thin films and their correlation with enhanced device performances are presented here. vacuum-deposited thin-film microstructure morphology NMeCy2 have been investigated using X-ray diffraction (XRD), atomic force microscopy (AFM), field emission scanning electron (FESEM) were comparable the bulk-phase crystalline structure packing NMeCy2. organic field-effect transistor (OFET) fabricated on a glass substrate consists bilayer polymer dielectric poly(methyl methacrylate) (PMMA) over poly(vinyl alcohol) (PVA) an inorganic high-k Al2O3 as third layer. thermally deposited at optimized temperature (Tsub) 60 °C displayed excellent molecular large area that resulted in improved performance mobility (μe) value 0.6 cm2 V–1 s–1 current on/off ratio (Ion/off) 106 v...
