Abstract :
The emissive properties of iridium field electron and ion emitters covered with various forms of carbon are studied. Observed peculiarities of Cs and K field desorption and field electron emission are explained using cesium atoms intercalation into graphite and graphene structures and release them under influence of electric field.
