Phosphorene: Enhanced Photoresponse from Phosphorene–Phosphorene‐Suboxide Junction Fashioned by Focused Laser Micromachining (Adv. Mater. 21/2016)
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. Once the junction is formed, the photoresponsivity and photocurrent distribution of the device can be significantly altered with a qualitative difference in behavior. Photovoltaic‐like behavior is observed, which is not found in the pristine sample.
