"all-stacking optimized interaction between 2D materials and metal electrodes through contact vdW forces... avoids introducing numerous defects... better operability, scalability... sharp metal-semiconductor contact interfaces, smooth and clear vdW gaps at interface, no metal atom doping on 2D material side... >95% reduced off-state current, 50% decreased subthreshold swing... higher on-off ratio favoring low-power ICs, excellent consistency, stability... 2D electronic devices"
