Effective Passivation of Exfoliated Black Phosphorus Transistors against Ambient Degradation
Effective Passivation of Exfoliated Black Phosphorus Transistors against Ambient Degradation
Unencapsulated, exfoliated black phosphorus (BP) flakes are found to chemically degrade upon exposure to ambient conditions. Atomic force microscopy, electrostatic force microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy are employed to characterize the structure and chemistry of the degradation process, suggesting that O2 saturated H2O …
