Abstract

Layered black phosphorous has recently emerged as a promising candidate for next generation nanoelectronic devices. However, the rapid ambient degradation of mechanically exfoliated black phosphorous poses challenges in its practical implementation in scalable devices. As photo-oxidation has been identified as the main cause of degradation, to-date, the strategies employed to protect black phosphorous have relied upon preventing its exposure to atmospheric oxygen. These strategies inhibit access to the material limiting its use. An understanding of the effect of individual wavelengths of the light spectrum can lead to alternatives that do not require the complete isolation of black phosphoro..
