A high-brightness large-diameter graphene coated point cathode field emission electron source
There have been several long-standing problems of cold field emission sources for electron microscopy and lithography that have prevented their widespread use, such as their inherent ultrahigh vacuum condition requirement (<10(–9) torr), relatively poor current stability and rapid emission decay....
