Thermally Driven Field Emission from Zinc Oxide Wires on a Nanomembrane Used as a Detector for Time-of-Flight Mass Spectrometry

ACS Omega have published an article by Haugg et Al discussing the ability to use low-dimensional nanostructures to achieve performance in mass spectrometry.  A simullation framework was developed to investigate the effect of wire length and diamter on the field emission. Findings suggest that there is a significant improvement in the FE response of the membrane by growing zinc oxide wires on top. These findings of enhanced FE could “facilitate the future application of detectors in mass spectrometry with properties improved by low-dimensional nanostructures.”

An array of zinc oxide wires were grown directly onto Silson’s silicon nitride membranes of 30 nm thickness for the mass spectrometry measurements.
