Phosphorene: Enhanced Photoresponse from Phosphorene–Phosphorene‐Suboxide Junction Fashioned by Focused Laser Micromachining (Adv. Mater. 21/2016) [PDF]

Advanced Materials, 2016
On page 4090, B. Özyilmaz, C. H. Sow, and co-workers use a focused laser beam to modify the surface of a phosphorene device. With a simple focused laser beam, a part of the phosphorene can be scanned and converted into phosphorene-suboxide species, leaving behind a functional and active phosphorene-phosphorene suboxide junction in the device.
