| Abstract;The electronic field emission phenomenon and its principle were explained. Recent advance on the thermal field electron source was outlined. The work function of the W(100) surface is selectively reduced by processing the surface with yttrium and with oxygen. The reduced work functions is 2.1eV and it is 0.6eV smaller compared with the ZrO/W(100) thermal field emission. By processing the surface with zirconium and oxygen again, the work function of molybdenum is also reduced on (100) surface selectively. The reduced work function is 2.0eV. In addition, the potentaial abilities of future the field emission cathode arrays (FEA) which accumulated the minute field emission cathode and the carbon nano-tubes for electron sources are explained and they are produced with the application of the semiconductor fine processing technology. |
