Tungsten which is one of high melting metal is employed as the material of the electron source. The work function of tungsten (100) surface is 4.6 eV. Although the work function is high value relatively, the value can be reduced to 2.7 eV selectively by the surface modification. ZrO/W (100) electron source using this phenomenon is used widely for electron beam system, e.g. critical dimension SEM. Also the phenomenon is occurred by modification of oxygen and 3 group element or 4 group element instead of zirconium and oxygen. In this research, we measured the work function of tungsten surface modified by scandium oxide, praseodymium oxide, and neodymium oxide by using field emission microscopy. |
