Tantalum nitride field emitters are fabricated by nitrifying a tantalum tip
which give an electron emission current of 210μA at the tip voltage of 6.8 kV and the temperature of 1300℃. with a brightness of 2×108 A/cm2. str and an angular current density of 5× 103 μA/str. The current fluctuation is small at the pressure of 10-8Torr. Typical field emission patterns are presented with a dark region at the center and two symmetrical bright regions on both sides. The composition of tip surfaces is analysed by a scanning Auger mic-roprobe.
