Publisher Correction: Soft-lock drawing of super-aligned carbon nanotube bundles for nanometre electrical contacts

The assembly of single-walled carbon nanotubes (CNTs) into high-density horizontal arrays is strongly desired for practical applications, but challenges remain despite myriads of research efforts. Herein, we developed a non-destructive soft-lock drawing method to achieve ultraclean single-walled CNT arrays with a very high degree of alignment (angle standard deviation of ~0.03°). These arrays contained a large portion of nanometre-sized CNT bundles, yielding a high packing density (~400 µm −1 ) and high current carrying capacity (∼1.8 × 10 8 A cm − 2 ). This alignment strategy can be generally extended to diverse substrates or sources of raw single-walled CNTs. Significantly, the assembled CNT bundles were used as nanometre electrical contacts of high-density monolayer molybdenum disulfide (MoS 2 ) transistors, exhibiting high current density (~38 µA µm −1 ), low contact resistance (~1.6 kΩ µm), excellent device-to-device uniformity and highly reduced device areas (0.06 µm 2 per device), demonstrating their potential for future electronic devices and advanced integration technologies.
