1. Researchers from USTC developed an all-stacking technique for integrating 2D materials with van der Waals (vdW) contacts, avoiding damage from traditional metal deposition. 2. This technique significantly improves the electrical performance of 2D electronic devices, reducing off-state current by 95% and enhancing on-off ratios. 3. The high yield and consistency of devices made using this method demonstrate its potential for large-scale industrial manufacturing.
