Figure 11From: Highly conductive vertically aligned molybdenum nanowalls and their field emission propertyField emission properties of Mo nanowall films with an area of 0.02 cm2on stainless steel substrate. (a) The J-E curves measured at different vacuum gaps (denoted). (b) The corresponding F-N plots. (c) The emission stability curve of the sample. The inset is the emission site distribution image.Back to article page
