Abstract: A cold cathode emission structure consists of a base electrode 102, an insulator layer 103, a gate electrode layer 104 and emission tips 105. A layer of fusible material 61 is located between the emitter tips and the base electrode. The structure is designed for use in an electron gun such as in a flat screen display device. In another embodiment the insulator layer is located between the gate and main electrodes.
