“…Due to their small diameter and excellent transport properties, single-walled carbon nanotubes (CNTs) are a particularly attractive candidate. 4 While serious integration challenges remain, recent successes with gate-all-around geometries and sub-10 nm channel lengths are extremely encouraging. [5][6][7] Although the progress is impressive, the remaining technological barriers and process variation, including difficulty in assembling CNTs with a controlled pitch, imperfect semiconducting purity, on-state current (I on ) variation, threshold voltage (V t ) variation, 8 and contact resistance, 9 still limit the performance.…”
