| Abstract Scope |
Inkjet 3D printing offers opportunities for additive manufacturing of multi-material electronic devices, which we successfully demonstrated previously with a variety of low dimensional material heterostructures: 2D/2D [Adv. Funct. Mater. 31, 2007478, 2021], 0D/2D [Nanoscale 15, 2134, 2023], 2D/polymer and 0D/polymer [Addit. Manuf. 66, 103452, 2023]. However, the performance of these devices strongly relies on the quality of the printed material interfaces, which are yet to be fully explored and understood. We explored the interfaces of inkjet-printed heterostructures based on combinations of 2D (graphene, hBN) and 0D (perovskite nanocrystals and metal nanoparticles) materials, and also conductive (PEDOT:PSS) and dielectric [PVP, PEG] polymers using complementary Time-of-Flight Secondary Ion Mass Spectrometry and Focused Ion Beam-Scanning Electron Microscopy, revealing infiltration and intermixing between layers. Furthermore, we examined the effects of the layer composition and deposition/post-deposition parameters on the quality of the interfaces, seeking to establish strategies for control of the interface properties. |
