Abstract |
The sputtering condition of Cr thin film was established in order to get Cr gate electrode having a vertical wall structure for Mo-tip FEA. In case of Mo-tip FEA which had a vertically-etched Cr gate electrode, the field enhancement factor, was relatively increased and so the field emission performance in terms of turn-on voltage, emission current and trans-conductance could be improved when compared with the devices having a tapered gate wall. |
