Phys Chem Chem Phys. 2016 Apr 28;18(17):12163-8. doi: 10.1039/c6cp01087c.The optimization of dual dielectric layers by incorporating poly(vinyl alcohol) (PVA), poly(methyl methacrylate) (PMMA), polystyrene (PS) or poly(4-vinylphenol) (PVP) in combination with Al2O3 resulted in immensely improved OFET characteristics with N,N'-bis(cyclohexyl)naphthalene diimide (NDI-CY2) as the active material. The influence of the polymer dielectric layer on the growth morphology of NDI-CY2 and the structural characterization were investigated using atomic force microscopy (AFM) and thin film XRD analysis.
