Inkjet-printed coplanar FET on PET. a Schematic of a printed coplanar FET heterostructure. HAADF-STEM cross-sectional view of the regions in the red dashed line (b) and blue dashed line (c). Multivariate analysis of the cross section in the blue region showing non-negative matrix factorization loadings and factors (insets) (d–i). The red box in g indicates the presence of the carbon (i.e. graphene) film. j Raman Spectroscopy of the printed coplanar FET heterostructure
