Reducing virtual source size by using facetless electron source for high brightness
Brightness of an electron source is key for the high spatial resolution of electron microscopy and analysis. A small source size is essential for high brightness, and it has been achieved by using small crystal facets; however, the emission current is reduced when the facet area is decreased. To ach...
