Extended Data Fig. 2: Process flows of EDL transfer and examples.
From: Electrostatic-repulsion-based transfer of van der Waals materials
a–f, Schematics showing the general process flow of EDL transfer. The key step is to detach vdW materials from substrates using EDL repulsion force by simply immersing the vdW materials/substrates into 32 wt% concentrated ammonia solution. The choice of support layer is not restricted in EDL transfer. g, Process flow showing the transfer of 2-inch MoS2 using EDL with only PMMA as the support layer. h, Process flow showing the multilayer stacking of MoS2 using EDL transfer with PDMS as the support layer. Scale bar, 1 cm. The process flow of using TRT + PMMA is similar to that using PDMS. See Methods for more details.
