Schwarzer Phosphor ist ein Schichtmaterial, das sensibel auf die Eigenschaften der umgebenden Atmosphäre reagiert. In der Zuschrift auf S. 14525 ff. verwandeln M. Pumera et al. diese Sensitivität in einen Vorteil und entwickeln einen auf schwarzem Phosphor basierenden Gassensor zum Nachweis von Methanol. Zur selektiven und reproduzierbaren Quantifizierung der Methanolkonzentration wird die Impedanzphase...
Black phosphorus is a layered material that is sensitive to the surrounding atmosphere. This is generally considered as a disadvantage, especially when compared to more stable layered compounds, such as graphite or MoS2. This sensitivity is now turned into an advantage. A vapor sensor that is based on layered black phosphorus and uses electrochemical impedance spectroscopy as the detection method...
