First principle studies revealing the effect of O2, CO2, and H2 adsorption on field emission behaviour of graphene

Field emission from sharp protrusions of graphite fabricated by sandblasting process

“…4) Carbon-based materials are particularly promising as field-emission electron source materials due to their unique shape and physical properties. [5][6][7][8][9][10][11][12] Among them, graphite is of particular interest due to its high electrical conductivity and crystallinity, and has been actively investigated as a field emitter. [13][14][15] Previous studies have reported field-emission properties from both industrial and nanoparticle graphite 13,14) as well as cone-shaped emitters fabricated from graphite using laser processing.…”
