Noninvasive Photodelamination of van der Waals Semiconductors for High‐Performance Electronics
Noninvasive Photodelamination of van der Waals Semiconductors for High‐Performance Electronics
Atomically thin 2D van der Waals semiconductors are promising candidate materials for post-silicon electronics. However, it remains challenging to attain completely uniform monolayer semiconductor wafers free of over-grown islands. Here, the observation of the energy-funneling effect and ambient photodelamination phenomenon in inhomogeneous few-layer WS2 flakes under low-illumination fluencies down to …
