The performances and operation lifetime of field emission (FE) cathodes made by spray-coating three different nanocarbon materials—carbon nanotubes (CNTs), graphene (GE), and carbon nanocoils (CNCs)—were compared. Though CNTs had the benefits of the lowest turn-on field, CNCs exhibited the most stab...
