Development of printed electronics requires understanding and control the interfaces in heterostructure devices. However, investigation between dissimilar materials to achieve intermixing presents challenges. Here, we report inkjet heterostructures by time-of-flight secondary ion mass spectrometry (ToF-SIMS), focused beam scanning electron microscopy (FIB-SEM), energy dispersive X-ray (EDX) analysis provide complementary insights into phenomena. By examining various 0D (CsPbBr3 nanocrystal), 2D (inkjet graphene, iGr), polymeric (PEDOT:PSS) deposited with different printing parameters, established effect ink composition parameters on depth. We demonstrated that where is dominated layer porosity, depth does not affect electrical properties device, while redispersion results decrease effective thickness accompanied an increase resistance. The strategy for over interfacial morphology could enable improved design performance
