Introduction Two-dimensional materials offer promising avenues to advance Moore's Law. In recent years, the research on electrical devices based on these materials has gained consi derable attention. When fabricating two-dimensional electrical devices, transferable metal electrodes can establish van der Waals contacts with two-dimensional materials through mechanical stacking. This approach effectively prevents damage caused by traditional micro/nano fabrication processes, thus improving device yield. Moreover, transferable metal electrodes provide a convenient, ready-to-use solution compatible with the transfer techniques commonly employed in two-dimensional material research. This enables rapid processing and fabrication, significantly enhancing the performance of two-dimensional electrical devices. Instructions for Use This process mirrors the techniques used in transferring two-dimensional materials: 1. Transfer: Utilize the transfer platform to precisely align and stack the transferable metal electrodes onto the target substrate (sample). 2. Adhesion: Heat the assembly to 150°C and maintain this temperature for 15 minutes to ensure a secure bond between the adhesive layer and the electrodes with the target substrate. 3. Peeling: While maintaining the temperature at 150°C, lift the glass slide with the electrodes. Use tweezers to carefully peel off the PDMS from the target substrate. Discontinue heating once the peeling process is complete. 4. Debonding: Remove the adhesive layer by soaking the assembly in acetone for five minutes. Alternatively, the adhesive layer can be left in place as a sealing layer. Pro Tip: For optimal performance, we recommend annealing the device post-transfer to minimize contact resistance Show more
